The Benefits of Drip Irrigation

<div style="margin: 0 auto; width: 680px;"> <div style="margin: 0pt; padding: 0pt; float: left; width: 322px;"> <br /><br />Drip irrigation is the slow application of water directly to the root zone of the plant, resulting in less water lost to evaporation in the sun and wind. The root zone is maintained at the ideal moisture level combining the proper balance of water and air. All of these factors promote deeper penetration of the roots, more foliage growth and abundant flower and fruit production! <h3 class="bottomout">Water Efficiency:</h3> Drip irrigation applies water only where it is needed, with less runoff and evaporation. Studies on drip irrigation systems are show results of up to 60% more efficiency over sprinkler systems. ~ <small><em><a href="http://www.uri.edu/ce/healthylandscapes/dripirrigation.htm%20" target="new">University of Rhode Island</a></em></small><br clear="all"> <img src="/images/DS20L/liontail.jpg" alt="" style="border: 1px solid rgb(0, 0, 0); margin: 15px auto 10px; padding: 0pt;" border="0" height="130" hspace="0" vspace="0" width="282"> <h3 class="bottomout">Conserves<br> Earth's Resources:</h3> Population is on the rise making it critically important to evaluate how each individual uses our earth’s precious resources, especially life giving water. In the heat of summer often times over half of the water used by a household goes to irrigation of the landscape. Everyone would like to have a beautiful garden. We encourage you to make educated decisions about how they are maintained. For example, conventional sprinkler heads measure water applied in GPM, or Gallons Per Minute. Drip emitters and micro sprinklers measure water applied in GPH, or Gallons Per Hour. Drip irrigation uses less water, and promotes lush plant growth: both offering our planet a beautiful and abundant future. <h3 class="bottomout">Reduced<br> Pest & Weed Growth:</h3> Watering only the roots of plants with drip irrigation reduces the amount of "pests" found on the plant. Wet foliage allows bugs and fungal pathogens like powdery mildew to thrive. Drip irrigation prevents this because it only waters the roots keeping the foliage dry and healthy. Directly watering the roots also inhibits germination of weeds because the area between plants is not wet, like with a sprinkler system. <h3 class="bottomout">Root Zone:</h3> One of the most important aspects of installing a new drip irrigation system is that a totally new and more favorable environment in the root zone is created, which maintains a relatively constant soil moisture level. This creates stress free plants that actively grow and resist disease. </div> <div style="margin: 0 0 0 36px; padding: 0pt; float: left; width: 322px;"> <img src="/images/DS20L/soakptrn.png" alt="drip root zone illustration" title="drip root zone illustration" style="margin: 25px 0 0 50px;" border="0" height="207" hspace="6" width="200"> <h3 class="bottomout">Long Life:</h3> All DIG products are designed to withstand the harshest conditions in both home and commercial installations. They are manufactured from high quality, durable plastics and contain added quantities of the compound Carbon Black, making them resistant to the damaging effects of ultraviolet rays. <h3 class="bottomout">Versatility:</h3> Low volume irrigation systems are designed for placement in both new and existing landscapes. They are also ideal for installation on difficult terrain such as on slopes, in oddly shaped areas, and sites with high winds. <br /><img src="/images/DS20L/pop-up-bod.jpg" alt="" border="0" height="138" hspace="0" vspace="0" width="271" style="margin: 15px 0 0 0;"> <h3 class="bottomout">Cost Savings:</h3> Investing in a low volume irrigation system can save money by significantly lowering water use in the garden, in turn lowering water utility bills. <h3 class="bottomout">Ease of Installation:</h3> Installation is a very simple process, no special tools or glue are needed. The only tools required to install an entire system are scissors and a tubing punch. </div><br clear="all"> </div> 0

<div style="width: 600px; margin: 0 auto;"> <h3 class="bottomout">Getting Started</h3> Compared to conventional sprinkler systems, drip irrigation systems are simple to design, inexpensive, and easy to install. Traditional high volume, high pressure sprinkler systems require careful planning, extensive trenching, and special tools and glues. Drip irrigation systems can be easily installed above or below ground, without special tools and glue or extensive technical knowledge. These efficient systems deliver water measured in Gallons Per Hour (GPH), and apply water only where it is needed. This can improve plant health, conserve water, and reduce the growth of weeds all at the same time. In addition, drip irrigation can reduce disease problems associated with moisture on the leaves of plants. <br /><img src="/images/DS20L/drip_irrigation_beni_17.jpg" alt="home residance drip irrigation system" width="600" height="403" style="z-index: 1;"> <table summary="ben of drip" border="0" width="600" style="margin: -2px 0 0 0; padding: 0; z-index:10;"> <tr> <td style="border-color: black; border-width: 1px 1px 1px 1px; border-style: solid; text-align: center;">Adjustable drippers or micro sprinklers</td> <td style="border-color: black; border-width: 1px 1px 1px 1px; border-style: solid; text-align: center;">PC button drippers to shrubs</td> <td style="border-color: black; border-width: 1px 1px 1px 1px; border-style: solid; text-align: center;">Drippers or misting sprayers for hanging plants</td> <td style="border-color: black; border-width: 1px 1px 1px 1px; border-style: solid; text-align: center;">4- or 6- outlet drip heads or 12-Outlet Maverick™ to retrofit 1/2" riser</td> <td style="border-color: black; border-width: 1px 1px 1px 1px; border-style: solid; text-align: center;">Micro sprayers for flowerbeds </td> <td style="border-color: black; border-width: 1px 1px 1px 1px; border-style: solid; text-align: center;">Brown PC Dripline or drip soaker tape for a vegetable garden </td> </tr> </table> <h3 class="bottomout">Planning and Designing a Low Volume Irrigation System </h3> When designing an irrigation system we first recommend considering the various areas and plants to be watered. We suggest using drip irrigation on trees, shrubs, vines, vegetables, flowerbeds, containers, pots, boxes, house foundations, on any individual plant, and narrow planting areas. Micro sprinklers are best used on groundcover, flowerbeds, groups of plants, hillsides and on very sandy soil. In sandy soil water will percolate downward when using drip before it can spread far enough horizontally; micro sprinklers will solve this problem because of the wide spray diameters. Avoid using micro sprinklers in windy areas. High winds will disturb the micro sprinkler spray pattern. <h3 class="bottomout">CREATE A PLANT LIST <small>( <a href="/downloads/DIG-Planning-Graph.pdf" target="new" class="und">download our pdf graph</a> ) </small></h3> First, note and list the locations of small and large trees, shrubs, groundcover, flowerbeds, containers and vegetable gardens. Then divide the plants into groups with similar watering needs, and plants that are in full sun or in a shaded areas. Next, take into consideration the soil type, and concentration of plants. Use this information to select the water emission devices and to estimate the total flow rate (see the example below Ref: htd1). <h3 class="bottomout">Design Layout Example (Ref: htd1)</h3> <img src="/images/DS20L/drip_irrigation_beni_20.jpg" alt="" width="600" height="545"> <h3 class="bottomout">About the Soil </h3> <img src="/images/DS20L/drip_irrigation_beni_20b.jpg" alt="" width="231" height="137" align="right">Soil is like a storage room for plant nutrients. It is the medium through which water and nutrients move. It anchors plants and is a reservoir of water for plant growth. There are various types of soil with different characteristics which determine what types of drippers or micro sprinklers Sandy Loamy Clayshould be used. In sandy soil, where water will tend to go straight down, use closely spaced 2 GPH drippers at 10-12" apart, or micros sprinklers in a wider spacing. In loamy soil, the water will move slowly and will spread evenly, so use 1 GPH drippers with 16-18" spacing. In clay soil, where water will be absorbed very slowly, use .5 GPH or 1 GPH drippers at a wider spacing (18-24" apart) or micro sprinklers and sprayers with adequate spacing. <h3 class="bottomout">Determine Soil Types </h3> With a drip system, water is applied slowly to the root zone at a single point. The water is acted upon by the forces of gravity (downwards) and capillary action (outwards), producing a wetting pattern characteristic of the soil type and the water application rate. To determine which type of soil you have in a given area, take a handful of dry soil, grip tightly and release. Sandy (coarse) soil will crumble and fall apart, loam (medium) soil will hold together but then easily break apart, and clay will mold without breaking. For more precise information, consider having a soil test conducted. Many universities offer this service through their extension offices and master gardener programs. <h3 class="bottomout">Sketch the Property or Area</h3> Start by making an accurate top view sketch of the areas that need to be watered (see Design Layout Example Ref: htd1 above). Be sure to add details such as the outline of the home, any retaining walls, sidewalks, paved areas, all the plants, and the water source locations accurately and to scale. <br /><br />This will require measuring the area. We recommend using graph paper with small squares. This will make drawing to scale easier. Each small square on the graph paper could represent one foot of the property; this scale is usually appropriate for residential landscapes. Modifications can be made as needed, such as 1" graph = 10'. ( <a href="/downloads/DIG-Planning-Graph.pdf" target="new" class="und">download our pdf graph</a> ) <h3 class="bottomout">Various Methods to Start a System </h3> Determining how to start a system, and what products to select, are important decisions that should be made carefully. The correct choice will depend on the size of the area, the availability of water outlets, the garden design/layout, and the type of plant material to be irrigated. Of the following five methods, choose the option(s) that is most feasible and appropriate for your particular use: <br><br>The typical home garden may require one or more watering zones.

To choose the correct emission device, please refer to the following guidelines: <br><br> <h2 style="display: inline;"><a href="javascript:void(0);" onclick="['tabPage6'].each(Element.toggle);">Category 1</a>: </h2> <h4 class="beni" style="display: inline;">Individual foundation trees and shrubs</h4> <div class="tab-page" id="tabPage6" style="display: none; padding-top: 5px;"> Pressure compensating (PC), button, adjustable and flag drippers are suited for virtually any layout with plants such as shrubs, trees, vines, roses. They are most efficient when plants are spaced few feet apart (See chart A1, B, and F below for recommended number of drippers, dripper spacing per plant or area and maximum length to run the 1/2" poly tubing and 1/4" micro tubing). Model G77 is an excellent starter kit for this type of installation.<br><img src="/images/DS20L/drip_irrigation_beni_29a.gif" alt="" width="577" height="130" /> <br><img src="/images/DS20L/drip_irrigation_beni_29b.gif" alt="" width="577" height="105" /> </div> <br><br> <h2 style="display: inline;"><a href="javascript:void(0);" onclick="['tabPage7'].each(Element.toggle);">Category 2</a>: </h2> <h4 class="beni" style="display: inline;">Densely planted flowerbeds, perennial beds and/or groundcover areas</h4> <div class="tab-page" id="tabPage7" style="display: none; padding-top: 5px;"> Micro sprinklers and micro sprayers are best suited for densely planted flowerbeds, annuals, groundcovers, groups or clusters of plants, small slopes, and on sites with very sandy soil. In sandy soil water will percolate downward before it can spread far enough horizontally (see charts A1, B and F, below for recommended spacing, flow rates, diameter, pattern, and maximum length to run 1/2" poly tubing). Avoid micro sprinklers in areas where it is windy; high winds will disturb the micro sprinkler's spray pattern.

<div style="width: 600px; margin: 25px auto 0 auto;"> DIG provides an extensive line of micro irrigation products and accessories including controllers, starter kits, drip emitters, dripline, micro sprinklers, foggers, tubing, fittings, and accessories to complete new and existing systems. <h4 style="margin-bottom: 0px;"><a href="/DIY/215-Battery_&_AC_Controllers/diy_products" >AC Controllers</a></h4> <img src="/images/DS20L/drip_irrigation_beni_55.gif" alt="" width="72" height="71" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />A controller should be selected with care. This is especially true if the irrigation system is watering a combined drip and sprinkler system with different settings for each valve or zone. DIG models 8004 (four station) and 8006 (six station) controllers are very simple to program. Both allow for each valve in the system to be programmed independently, from 1 minute to 12 hours in one minute increments. They both have four start times for each valve allowing for mixed irrigation applications for drip and sprinkler systems. <h4 style="margin-bottom: 0px;"><a href="/DIY/215-Battery_&_AC_Controllers/diy_products" >Battery Operated Controllers</a> </h4> Battery operated controllers and timers are ideal for any watering system that needs to be automated without connecting wire to an AC source. These controllers have a wide range of features and use one 9-volt battery, with a battery life of up to two years. <br><br> <h4 style="margin-bottom: 0px;"><a href="/DIY/215-Battery_&_AC_Controllers/diy_products" >Battery Operated Controllers: Hose End and In-line</a></h4><img src="/images/DS20L/drip_irrigation_beni_59b.gif" alt="" width="131" height="71" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_59a.gif" alt="" width="74" height="71" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_59c.gif" alt="" width="106" height="71" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />Our hose end battery operated controllers are available with either hose or pipe thread, low flow or high flow, with LCD display or without, and are covered by a 3-year limited warranty. <h4 style="margin-bottom: 0px;"><a href="/DIY/215-Battery_&_AC_Controllers/diy_products" >Battery Operated Controllers: Anti-siphon</a></h4> <img src="/images/DS20L/drip_irrigation_beni_62a.gif" alt="" width="80" height="71" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_62b.gif" alt="" width="70" height="71" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />Anti-siphon valves prevent irrigation water from flowing back to the main water source. DIG anti-siphon battery operated controllers are used for above ground installation and are available with either a 3/4" anti-siphon valve or with a retrofit actuator to convert most 3/4" or 1" manual anti-siphon valves on the market to automatic operation. <h4 style="margin-bottom: 0px;"><a href="/DIY/216-Starter_Kits/diy_products" >Starter Kits</a></h4><img src="/images/DS20L/drip_irrigation_beni_66.gif" alt="" width="125" height="82" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> DIG provides a variety of kits to help the first time user start a drip and/or micro sprinkler system, or to retrofit your existing sprinkler system to a multi-outlet drip system. DIG kits are the perfect way to get familiarized with the advantages and benefits using micro irrigation systems. For your convince DIG kits offer complete, fast and easy drip/micro sprinkler installation. All of our kits are easily expandable utilizing some of DIG's wide range of drip irrigation parts and accessories. <h4 style="margin-bottom: 0px;"><a href="/DIY/217-Head_Assembly/diy_products" >Head Assembly: Components for a Drip Zone</a> </h4> <img src="/images/DS20L/drip_irrigation_beni_77.gif" alt="" width="70" height="68" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />When installing a low volume irrigation system, using a filter and a pressure regulator will ensure that the system remains trouble free for years to come. Please remember: drip systems and micro sprinklers require clean water and operate at lower pressures than conventional sprinkler systems. <h4 style="margin-bottom: 0px;"><a href="/DIY/219-Drip_Tubing_&_Micro_Tubing/diy_products" >Poly Tubing and Micro Tubing</a></h4> <img src="/images/DS20L/drip_irrigation_beni_88.gif" alt="" width="70" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_89.gif" alt="" width="70" height="49" style="clear: right; float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>There are three sizes of drip tubing: 1/2" poly tubing, 1/4" and 1/8" micro tubing. The 1/2" poly tubing is most often used as the main lateral or mainline into which drippers, micro sprinklers, or 1/4" barbs to connect the 1/4" micro tubing are inserted. The 1/4" serves as the distribution line into which drippers or micro sprinklers are inserted. The 1/8" is used only with the Maverick™. DIG poly tubing and micro tubing is one made of the highest quality polyethylene or vinyl resin, with 5%+ Carbon Black added for extra resistance to the damaging effects of the sun's ultraviolet rays. Both the 1/2" poly tubing and the 1/4" micro tubing may be installed above or below ground. They are designed to meet the all the needs of both commercial and residential low volume irrigation users. <h4 style="margin-bottom: 0px;"><a href="/DIY/224-Drip_Fittings/diy_products" >1/2" and 1/4" Fittings</a></h4> <img src="/images/DS20L/drip_irrigation_beni_93a.gif" alt="" width="227" height="77" style="clear: right; float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Drip fittings are divided into three categories: compression, barb, and Universal Nut Lock™. The compression fittings are available in various configurations and connect to the 1/2" poly tubing. By using a simple wrist action, the tubing is 'walked" into the fittings for a very tight fit. No tools, glue, or clamps are required. DIG's compression fittings with black inserts are used with 1/2" poly tubing that is .700 OD. <BR><BR> Fittings are available to attach 1/4" micro tubing in straight barbs, elbows, and tees. The micro tubing is pushed over 1/4" fitting, or barb, to ensure a leak proof fit. The opposite end can be inserted into 1/2" poly tubing, or used to attach another piece of micro tubing. <br><br> DIG also has specialty fittings, such as the 1/2" PVC to polyethylene connectors, and a complete line of 1/2" compression fittings with blue inserts that can be used with TORO Blue Stripe™ drip hose that is .710 OD. <br><br><img src="/images/DS20L/drip_irrigation_beni_93b.gif" alt="" width="90" height="77" style="clear: right; float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/> DIG provides reducing couplings to convert from our 1/2" poly tubing to the following brands: To connect DIG poly tubing to Blue Stripe™ (.710 OD) use #14 with blue insert. To convert Raindrip® driphose to DIG poly tubing (.620 OD), use #15, with green insert. <h4 style="margin-bottom: 0px;"><a href="/DIY/224-Drip_Fittings/diy_products" >1/2" Universal Nut Lot™ Fittings</a></h4> <img src="/images/DS20L/drip_irrigation_beni_94.gif" alt="" width="70" height="49" style="clear: right; float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Nut Lock fittings use a combination of barb and compression to connect different sizes of poly tubing.DIG universal fittings are designed to connect any size of tubing from .620 OD to .710 OD; regardless of the brand these will make the connection fit.DIG Universal Nut Lock fittings are available in three configurations: #73 coupling, #74 tee,and #75 elbow.These fittings provide an additional way to connect poly tubing and can be easily disconnected and re-used if necessary. <h4 style="margin-bottom: 0px;"><a href="/DIY/221-Drip_Emitters/diy_products" >Pressure Compensating (PC) Buttons, Flags and Adjustable Drip Emitters</a></h4> <img src="/images/DS20L/drip_irrigation_beni_98.gif" alt="" width="70" height="62" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_99a.gif" alt="" width="70" height="62" style=" float:right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_99b.gif" alt="" width="70" height="62" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Drippers are the heart of any drip irrigation system. DIG drippers deliver a precise amount of water directly to the plant's root zone. They are reliable, accurate, inexpensive, and easy to install. They may be inserted directly into 1/2" poly tubing or extended to the plants using a 1/4" micro tubing. DIG drippers incorporate four different characteristics: PC, turbulent flow, laminar flow, and adjustable drippers. <h4 style="margin-bottom: 0px;"><a href="/DIY/220-Drip_Line__Drip-Soaker_Hose_&_Drip_Tape/diy_products" >Earthline Brown PC™ Dripline</a></h4> <img src="/images/DS20L/drip_irrigation_beni_101.gif" alt="" width="71" height="71"style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Earthline Brown PC™ Dripline is a drip hose that contains pressure compensating (PC) emitters incorporated into the interior wall of the tubing at 18" intervals. The emitters are pressure compensating and self-cleaning. This allows long runs and an extended life in the landscape. <br><Br> Both the tubing and the drippers are manufactured from quality resins using hi-tech equipment to form a product that withstands the various chemicals and fertilizers used in agriculture and landscaping. <br><br> The working pressure range for the Earthline Brown PC™ Dripline is from 10-50 PSI but to maintain optimum performance it should always be used with a 25 PSI pressure regulator. <br><br> Earthline Brown PC™ Dripline has a flow rate of 1 GPH and comes in 100' rolls. It can be used with DIG compression fittings. Earthline Brown PC™ Dripline can be used below or above the ground or mulch and is suitable for most types of plants. <h4 style="margin-bottom: 0px;"><a href="/DIY/220-Drip_Line__Drip-Soaker_Hose_&_Drip_Tape/diy_products" >Drip Soaker Tape, Soaker Hose & Accessories</a></h4> <img src="/images/DS20L/drip_irrigation_beni_106.gif" alt="" width="192" height="63"style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Drip soaker tape and 1/4" soaker hose are other methods of providing drip irrigation tovegetable gardens, window boxes, or where total saturation is desired along a straight,narrow path. The drip soaker tape is a flat drip tape with drippers pre-inserted every 12". Soakerhose is a 1/4" micro tubing with holes every 12". The drip soaker tape can be used above orbelow the ground and the soaker hose above the ground only. Maximum working pressure is 25PSI. We highly recommend installing a 25 PSI preset pressure regulator and a filter at thebeginning of the lines. <Br><Br> <b>NOTE:</b> Install drip soaker tape in straight lines ONLY.DRIP SOAKER TAPE FITTINGS: The drip soaker hose requires special drip soaker tape fittings ( #27, #28, #29, #76, #77 ) that are different in design from those used with 1/2" poly tubing, in that they workwith a twisting lock device rather than with compression. <h4 style="margin-bottom: 0px;"><a href="/DIY/222-Microsprinklers_&_Spray_Jets/diy_products" >Micro Sprinklers, Micro Sprayers & Foggers</a></h4> <img src="/images/DS20L/drip_irrigation_beni_116.gif" alt="" width="82" height="65"style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_117a.gif" alt="" width="82" height="65"style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_116.gif" alt="" width="82" height="65"style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Micro sprinklers, sprayers, and foggers are available in a variety of styles and configurations. Like drip emitters, micro sprinklers, sprayers, and foggers operate at low-pressure. Micro sprinklers, sprayers, and foggers are designed for areas where drippers may not be as practical, such as for groundcover, flowerbeds, large boxes, and oddly shaped areas. Micro sprinklers and sprayers are rated by flow rate, wetting diameter or radius, and the spray method (moving parts versus non moving parts). Like sprinklers, micro sprinklers and sprayers are available in 360° full circle pattern, 360° jet pattern, 180° half circle pattern, 90° quarter circle pattern, and strip patterns that aim left and right like a bow tie. DIG's micro sprinklers, sprayers, and foggers are available in a variety of flow rates and diameters from 2-42 GPH, with diameter from 1-42'. Micro sprinklers, sprayers, and foggers have small sized droplets and provide a low precipitation rate, allowing longer watering time with less runoff. <h4 style="margin-bottom: 0px;"><a href="/DIY/218-Retrofits_Drip_&_Accessories/diy_products" >Retrofit Drip Heads and Accessories</a></h4> <img src="/images/DS20L/drip_irrigation_beni_133c.gif" alt="" width="80" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_133b.gif" alt="" width="80" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_133a.gif" alt="" width="80" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>DIG's retrofit heads are designed to adapt any 1/2" riser above the ground. They may be incorporated into a new system, or used to convert an existing sprinkler to a 4, 6, or 12-outlet drip system without disturbing the flow of the other sprinklers on the line. <br><Br> Retrofitting conventional sprinkler systems to low flow water saving drip systems requires a few simple steps: <br><br> First, Evaluate the areas to be watered. While large areas such as lawns are best watered bysprinklers, other areas, such as shrubs, trees, roses, or individual plants, can be irrigated moreefficiently by using the retrofit drip heads. Second, remove the sprinkler head from the riser, flushthe line and screw the Maverick™ 12-outlet, 6-outlet, or 4-outlet drip heads onto the riser. Third, extend the micro tubing from the drip head to the plants and secure micro tubing with a 1/4"stake ( #67 ). <h4 style="margin-bottom: 0px;"><a href="/DIY/225-Accessories/diy_products" >Accessories</a></h4> Drip systems use many different types of accessories, which are separated into two categories: necessary and customizing. Some are necessary for the installation of drip systems, such as a goof plugs and hose ends. Others, such as in-line valves, drip inserts and "C" clamps, are for customizing the system. <br><br> <h2 class="tab">Category 1</h2> <h4 style="margin-bottom: 0px;">Necessary Parts:</h4><img src="/images/DS20L/drip_irrigation_beni_137a.gif" alt="" width="102" height="62" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_137b.gif" alt="" width="102" height="62" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_137c.gif" alt="" width="102" height="62" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>These are parts that are needed to initially install a drip system. #51 and #52 - Punches are used to punch holes in the poly tubing for the insertion of drippers and micro sprinklers. #55, hose end is used to close the end of 1/2" poly tubing. #56, goof plugs are used to plug up unwanted holes. #57 and #67, tubing stake holders are used to secure the position of the drippers to the micro tubing near the plants. #60, tubing holder stakes are used to hold 1/2" poly tubing in place on the ground. #66, ray spike or #68, universal spike assemblies are used to hold micro sprinklers or sprayers above the ground. <h2 class="tab">Category 2</h2> <h4 style="margin-bottom: 0px;">Customizing Parts</h4><img src="/images/DS20L/drip_irrigation_beni_138b.gif" alt="" width="102" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_138a.gif" alt="" width="103" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_138c.gif" alt="" width="103" height="57" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>Other drip accessories are available to customize a system and the specific needs of the site.

<div style="width: 600px; margin: 25px auto 0 auto;"> When installing a micro irrigation system, there are various start-up options, layouts and configurations. Choose the option that best suits the needs of the landscape. <h3 style="margin-bottom: 0px;">Head Assembly Installation </h3> All properly designed drip systems begin with what is called the "head assembly". This consists of three vital components: a control valve (manual or automatic), a filter, and a pressure regulator. This assembly can be attached to a faucet, anti-siphon valve, in-line valve, or sprinkler riser. <br><br> <h2 style="display: inline"><a href="javascript:void(0);" id="show_downloads" onclick="['InstalltabPage1'].each(Element.toggle);">Option 1</a>: </h2> <h4 style="display: inline">BEGIN THE INSTALLATION BY CONNECTING TO AN OUTDOOR FAUCET</h4> <div class="tab-page" id="InstalltabPage1" style="display: none; padding-top: 5px;"> <img src="/images/DS20L/drip_irrigation_beni_185a.gif" alt="" width="250" height="183" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/><img src="/images/DS20L/drip_irrigation_beni_185b.gif" alt="" width="220" height="183" style="float: right; clear: right; margin: 0 15px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;"/>First attach the #10 backflow device (if the faucet already has a brass backflow attached, #10 is not required). Then attach the #13 filter (or #12 fertilizer applicator with backflow device included). Next install a #4 pressure regulator followed by the #18 -3/4" swivel adapter (see figure 2). <br><Br>If using a battery operated timer ( model 9001 and 9001EZ ), install the backflow device after the timer (see figure 2a). All these fittings have "hose" type threads and are sealed by a washer. They should be turned clockwise until they are "hand tight" only. Tightening with a wrench is not recommended and should not be necessary. <div class="clear"></div> </div> <br clear="all"><br> <h2 style="display: inline"><a href="javascript:void(0);" id="show_downloads" onclick="['InstalltabPage2'].each(Element.toggle);">Option 2</a>: </h2> <h4 style="display: inline">BEGIN THE INSTALLATION CONNECTING TO AN EXISTING MAINLINE</h4> <div class="tab-page" id="InstalltabPage2" style="display: none; padding-top: 5px;"> (Note: This method requires basic plumbing skills - inexperienced installers should contact a plumber or irrigation contractor for this connection). <br><br> <h4 style="margin-bottom: 0px;">First, tap into the water service line.</h4> This can be done at a faucet or by cutting into the service line before the faucet. You can avoid cutting the service line by removing the faucet and installing a brass threaded "tee" (line size) just up stream of the faucet (see figure 3). Shut off the water supply and unscrew the faucet from the brass fitting or, if necessary, cut the copper pipe before the faucet. Install the tee with the side outlet facing down and screw the faucet back into the end of the tee. Next, below the tee install a manual shutoff valve (for emergencies), then 3/4" PVC male adapter, then connect 3/4" PVC pipe and run it out to the location of the drip system control valve(s). (Copper should be used in areas that freeze). <h4 style="margin-bottom: 0px;">Select which type of control valve to install</h4> <img src="/images/DS20L/drip_irrigation_beni_188a.gif" alt="" width="220" height="163" style="float: right; clear: right; margin: 0 15px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />DIG provides several different types of automatic control valves; each one is designed for the low-flow hydraulic needs of drip systems. If the design calls for more than one control valve, use the same type for each zone. This may involve building a manifold with a series of tees branching off to each valve. Always end the manifold with a PVC cap to make future valve additions easier. Choose either in-line battery operated valves ( #7001 ), in-line AC (electric) valves ( #DM075 ), battery operated anti-siphon valves ( 2008I ), or manual anti-siphon valves. Please note that AC valve installations will involve running underground control wires back to an electric controller. <br clear="all"><br> <h2 style="display: inline"><a href="javascript:void(0);" id="show_downloads" onclick="['InstalltabPage3'].each(Element.toggle);">A</a>: </h2> <h4 style="display: inline">Underground installation using in-line battery operatedcontroller</h4> <div class="tab-page" id="InstalltabPage3" style="display: none; padding-top: 5px;"> <img src="/images/DS20L/drip_irrigation_beni_188b.gif" alt="" width="220" height="137" style="float: right; clear: right; margin: 0 15px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />Use controller model 7001 and complete the headassembly by attaching a #6 MNPT filter and #5 pressure regulator.

Next attach a #4 pressure regulator (hose thread) and finally the #18 3/4" swivel adapter. Now connect either 1/2" polytube or Earthline Brown PC™ dripline and secure the tubing or the dripline using #60 tubing holder stake. When combining drip irrigation with an existing sprinkler system, be sure to use high flow #34 4 GPH drippers or #39 adjustable drippers with flow between 0-20 GPH. After installing the drippers, open the valve and flush out the line. Then close off the end with a #71 end cap or #55 figure "8" hose end. <br><br> If used with 1/4" micro tubing, after the pressure regulator, add a #21 adapter. Next connect the 1/4" micro tubing, and add #26 1/4" tees as needed. Use with #34 drippers (4 GPH) to a maximum flow rate of 35 GPH </div> <h3 style="margin-bottom: 0px;">Choosing Lateral Layout Installation </h3> <h4 style="margin-bottom: 0px;">INSTALLATION METHOD USING POLY TUBING AS THE MAIN LATERAL:</h4> Install the 1/2" poly tubing above or below grade from the hose end, in-line controller, or in-line valve to the area to be watered. Use #19 1/2" tees and #20 elbows where needed. From the tee or elbow extend additional poly tubing to the plant area. Secure all 1/2" poly tubing to the ground using #60 holder stakes. Use 1/4" micro tubing as the feederline and add drippers as needed. <h4 style="margin-bottom: 0px;">INSTALLATION METHOD USING A PVC PIPE AS THE MAIN LATERIAL:</h4><img src="/images/DS20L/drip_irrigation_beni_189b.gif" alt="" width="320" height="156" style="float: right; clear: right; margin: 0 15px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> Install a 3/4" PVC pipe below grade from the controller or in-line valve to the area to be watered. Connect the PVC pipe to the in-line valve or to the battery operated controller. In each area to be watered add a 3/4" PVC tee (3/4" slip x 1/2" FNPT), and to the tee add a 6-8" 1/2" riser. To the riser add a #63 conversion elbow, and then a #18 swivel adapter or #22 swivel tee. Attach the 1/2" poly tubing or Earthline Brown PC™ Dripline, and secure all 1/2" poly tubing and dripline to the ground using #60 holder stakes. Add drippers or micro sprinklers as needed to the 1/2" poly tubing or use 1/4" micro tubing as the feederline to the plants and add the drippers at the end of the micro tubing. <h4 style="margin-bottom: 0px;">1/2" POLY TUBING AND 1/4" MICRO TUBING INSTALLATION:</h4> Unroll the 1/2" poly tubing and lay it out in direct sunlight to warm it up and make it easier to work with. Use #60 stakes to secure the poly tubing to the ground. If the polytube is to be installed below grade, dig trenches 6-8" deep to keep the poly tubing a safe distance from cultivation practices. Leave the end of the poly tubing above the surface for periodic flushing. <br><Br> If the installation requires crossing under a concrete walk or driveway, first dig two holes on opposite sides of the walkway. Next, connect 3-5' of 3/4" PVC pipe to a garden hose, using #7 hose to pipe thread adapter and a 3/4" PVC FNPT x slip. Then turn on the water and begin forcing it through the soil. Be careful to avoid damage to the concrete walk or driveway. When the end of the pipe reaches the other side, turn off the water and cut the pipe so the hose and fittings can be removed. Now use the 3-5' PVC pipe as a sleeve and push the polytube through the pipe until it appears on the other side. <br><br> Once the 1/2" poly tubing has been installed, then the 1/4" micro tubing can be connected. First attach the micro tubing to the 1/4" barb or 1/4" tee, then use the #52 punch to make a hole in the 1/2" poly tubing. Insert the barb or tee into the hole. Install a dripper or micro sprayer at the end of the micro tubing and use it as a feederline to reach remote plants or clusters of plants that are away from the main 1/2" poly tubing. <img style="margin: 10px auto 0 auto; display:block; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" src="/images/DS20L/drip_irrigation_beni_192a.gif" alt="" width="582" height="113" /> <h4 style="margin-bottom: 0px;"><img src="/images/DS20L/drip_irrigation_beni_192b.gif" alt="" width="232" height="111" style="float: right; clear: right; margin: 0 15px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />COMPRESSION FITTING INSTALLATION:</h4> To connect 2 pieces of 1/2" poly tubing use compression fittings. Hold the fitting in one hand and the tubing in the other and force the tubing into the fitting by "walking" or "wiggeling" it into the fitting. Installation is complete when 1/2-3/4" of the tubing is inside the fitting. <br clear="both"> <img src="/images/DS20L/drip_irrigation_beni_192e.gif" alt="" width="184" height="111" style="float: right; margin: 5px 25px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_192d.gif" alt="" width="183" height="111" style="float: right; margin: 5px 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_192c.gif" alt="" width="183" height="111" style="float: right; margin: 5px 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><br clear="right"> To connect various sizes of 1/2" poly tubing with different ODs, use our reducer #14 coupling for TORO BLUE STRIPE™ and #15 for RAINDRIP™ or use Universal Nut Lock™ fittings #73 coupling, #74 tee and #75 elbow to connect any size of 1/2" tubing. Removing the nut and insert it over the poly tubing (any brand name). Insert the barb side of the nut lock into the ID side of the poly tubing, and insert the other side of the barb into the nut lock housing. Then thread the nut lock to secure. <h4 style="margin-bottom: 0px;">BARB FITTING INSTALLATION:</h4><img src="/images/DS20L/drip_irrigation_beni_192f.gif" alt="" width="234" height="111" style="float: right; margin: 0 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> Barb fittings are most often used to connect 1/4" micro tubing into 1/2" poly tubing. They are also used to connect two ends of 1/4" micro tubing. Insert the barb into the end of the 1/4" micro tubing by forcing the micro tubing over the 1/4" barb. To connect micro tubing to 1/2" poly tubing, first attach the micro tubing to a barb. Second, punch a hole in the poly tubing. Last, push the side of the barb without micro tubing into the hole. <br clear="all"><img src="/images/DS20L/drip_irrigation_beni_192i.gif" alt="" width="184" height="97" style="float: right; margin: 5px 25px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_192h.gif" alt="" width="184" height="98" style="float: right; margin: 5px 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_192g.gif" alt="" width="183" height="97" style="float: right; margin: 5px 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><br clear="right"> <h4 style="margin-bottom: 0px;">USING THE PUNCH TOOLS:</h4> DIG offers two different punches used to "punch" the holes in poly tubing for the installation of emitters, micro tubing, etc. Both are easy to use. When installing a small number of drip emitters, use the #52 basic punch. For a large number of emitters and for ease of installation, use the #51 deluxe punch that offers leverage and more accuracy. <br><br> To use the basic punch, hold the poly tubing in one hand. Hold the punch in the free hand and use it to apply pressure to the poly tubing. At the same time rotate the punch back and forth creating a hole in the poly tubing. To use the large deluxe punch, first insert the poly tubing into the punch. Then press the handle down to punch a hole.<br> <img src="/images/DS20L/drip_irrigation_beni_193c.gif" alt="" width="183" height="120" style="float: right; margin: 5px 25px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_193b.gif" alt="" width="183" height="120" style="float: right; margin: 5px 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_193a.gif" alt="" width="183" height="120" style="float: right; margin: 5px 0 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <h3 style="margin-bottom: 0px;">Drip Emitter Installation </h3> The drip emitters are installed using one of the two methods; either directly in the poly tubing or at the end of micro tubing. <h4 style="margin-bottom: 0px;">DIRECTLY INTO POLY TUBING:</h4><img src="/images/DS20L/drip_irrigation_beni_194.gif" alt="" width="234" height="128" style="float: right; margin: 0 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> When plants are close to the mainline install emitters directly into 1/2" poly tubing. Punch a hole in the 1/2" poly tubing. Snap the barb side of the dripper into the poly tubing. Make sure that the minimum spacing between the drippers is not less than 10". <br clear="both"> <h4 style="margin-bottom: 0px;" style="clear:right;">AT END OF MICRO TUBING:</h4><img src="/images/DS20L/drip_irrigation_beni_197.gif" alt="" width="234" height="128" style="float: right; margin: 0 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> The second method is used for plants that are far away from the 1/2" poly tubing, in a container or for foggers on mist lines. First measure a length of micro tubing from the mainline to the plant. Cut micro tubing and attach a barb to one end of micro tubing. Insert the barb into the 1/2" poly tubing mainline. Insert an emitter into the opposite end of the micro tubing and place close to the plant. Secure the dripper using a #57 or #67 micro tubing holder stake. <br clear="both"><img src="/images/DS20L/drip_irrigation_beni_198c.gif" alt="" width="182" height="111" style="float: right; margin: 5px 25px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_198b.gif" alt="" width="182" height="111" style="float: right; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_198a.gif" alt="" width="182" height="111" style="float: right; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><br clear="right"> <br clear="both"><img src="/images/DS20L/drip_irrigation_beni_198f.gif" alt="" width="182" height="111" style="float: right; margin: 5px 25px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_198e.gif" alt="" width="182" height="111" style="float: right; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_198d.gif" alt="" width="182" height="111" style="float: right; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <br clear="both"></div> 1

<div style="width: 600px; margin: 0 auto;"> <h3 style="margin-bottom: 0px;">Drip Installation in Landscape</h3> <img src="/images/DS20L/drip_irrigation_beni_201.gif" alt="" width="586" height="371" style="margin: 5px 0 10px 0;" /> <h3 style="margin-bottom: 0px;">Drip Installation in Vegetable Gardens</h3> When installing drip irrigation in a vegetable garden with rows more than 2' apart,run one line for each row.If the rows are less than 2' apart,run one line between every two rows.In both cases insert a dripper (1/2-1 GPH) every 12".It is helpful to stagger the emitters between rows for more complete saturation. <img src="/images/DS20L/drip_irrigation_beni_202.gif" alt="" width="586" height="371" style="margin: 5px 0 10px 0;" /> <h3 style="margin-bottom: 0px;">Drip Irrigation for Containers and Patio Gardens </h3> Patio and container systems are often made entirely from 1/4" micro tubing. Use a combination of drippers and misters, 1/4" tees, elbows and barbs. Do not exceed 35 GPH on any single 1/4" micro tubing system. See Kit FM01. <img src="/images/DS20L/drip_irrigation_beni_204.gif" alt="" width="586" height="342" style="margin: 5px 0 10px 0;" /> <h3 style="margin-bottom: 0px;">Drip Soaker Tape Installation </h3> <h4 style="margin-bottom: 0px;">INSTALLING DRIP SOAKER TAPE:</h4> Drip Soaker Tape can be installed easily either above or below the ground. It is mainly used in vegetable gardens or a long narrow row of vegetation. We recommend using 1/2" poly tubing as a mainline, running perpendicular to the garden rows. Connect the drip soaker tape to the #29 reducer. Punch a hole in the 1/2" poly tubing at the connection point of each row, and insert the barbed end of #29 reducer. After running the poly tubing down the row, use #28 end to close the end. For vegetable rows more than 2' apart, run one line of drip soaker tape per row. If the rows are less than 2' apart, place the drip soaker tape between every two rows. We highly recommend the use of a 25 PSI pressure regulator with this system. <br><Br> NOTE: Do not round corners with drip soaker tape. <img src="/images/DS20L/drip_irrigation_beni_205.gif" alt="" width="586" height="299" style="margin: 5px 0 10px 0;" /> <h3 style="margin-bottom: 0px;">Earthline Brown PC™ Dripline Installation </h3> <h4 style="margin-bottom: 0px;">EARTHLINE BROWN PC™ DRIPLINE INSTALLATION:</h4> Dripline can be installed below or above the ground. If used above the ground it can be covered with mulch to blend it with the landscape. Earthline Brown PC™ Dripline can be installed in planters, islands, or landscape areas. To connect the dripline to the poly tubing, use compression fittings #19 tee, or #20 elbow and close the end of the line using #71 end cap or #55 figure "8". To start Earthline Brown PC™ from a 1/2" PVC riser, first screw #63 conversion elbow onto the riser and attach a #4 pressure regulator. To the pressure regulator, attach a #18 3/4" swivel adapter. Connect the dripline to the swivel adapter. Lay the dripline in any configuration using #19 tees and #20 elbows. We recommend using dripline in 12-16" spacing between the lines on sandy soil, and 18-24" between the lines on loamy soil for the best coverage. <img src="/images/DS20L/drip_irrigation_beni_208a.gif" alt="" width="592" height="161" style="margin: 5px 0 10px 0;" /> <h3 style="margin-bottom: 0px;">Micro Sprinkler, Fogger and Sprayer Installation </h3> <img src="/images/DS20L/drip_irrigation_beni_208b.gif" alt="" width="116" height="155" style="float: right; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />DIG has a large selection of micro sprinklers, micro sprayers, and foggers with a wide range of patterns and flow rates. They are available with a stake assembly or threaded barb. (<a href="/DIY/208-Drip_Irrigation_design_and_Installation_Guide/pages/4#charts">See chart A1, B, and F</a> for details on spacing, coverage and flow rates). <h4 style="margin-bottom: 0px;">Mini Sprinklers and Micro Sprinklers:</h4> Mini sprinklers and micro sprinklers are available in 360° patterns, and are pre-assembled with 13" spike, and 24" micro tubing with barb for maximum installation flexibility. They offer uniform coverage with a 10-40' <img src="/images/DS20L/drip_irrigation_beni_208c.gif" alt="" width="249" height="350" style="float: right; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> wetting diameter. To install simply punch a hole in the 1/2" poly tubing and snap the 1/4" barb into the poly tubing. The micro sprinklers should be Bridge elevated a minimum of 8" above the ground for good uniformity and coverage. <img src="/images/DS20L/drip_irrigation_beni_208d.gif" alt="" width="145" height="270" style="float: left; margin: 5px 0px 5px 5px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_208e.gif" alt="" width="168" height="270" style="float: left; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <br clear="both"><h4 style="margin-bottom: 0px;">Micro Sprayers and Misters:</h4><img src="/images/DS20L/drip_irrigation_beni_209bb.gif" alt="" width="233" height="321" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> Micro sprayers are available with various spray patterns such as a flat strip, 90°,180°or 360°.Their wetting diameters are between 3-13'.The preassembled models install the fastest. Parts can also be purchased individually and assembled at installation. <img src="/images/DS20L/drip_irrigation_beni_209aa.gif" alt="" width="142" height="218" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />To do this use a combination of model #58 PE riser assembly with1/4" barb, #68 universal spike assembly with micro tubing and barb, or #69 adjustable stake assembly. To install either one, punch a hole in the 1/2" poly tubing and snap the 1/4" barb into the poly tubing. The micro sprayers should be raised a minimum of 4-8" above the ground for agood uniformity and coverage. <br clear="right"> <h4 style="margin-bottom: 0px;">ADJUSTABLE SPRAY JETS:</h4><img src="/images/DS20L/drip_irrigation_beni_209b.gif" alt="" width="226" height="344" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> Adjustable micro sprayers are available in 90°,180°and 360°spray patterns with an adjustable flow range of 0-20 GPH.Their wetting diameter can be up to 20'.Consider using them along the perimeter of pathways,on flowerbeds,or groundcovers.They can be installed into the 1/2" poly tubing using the spike assembly or some of our accessories such as model #58 <img src="/images/DS20L/drip_irrigation_beni_213a.gif" alt="" width="158" height="191" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />PE riser assembly with 1/4" barb,or #68 universal spike assembly with micro tubing and barb.Toinstall,punch a hole in the 1/2" poly tubing and snap the 1/4" barb of the assembly into the poly tubing.The adjustable micro sprayers should be raised a minimum of 4-8" above the ground for good uniformity and coverage. <h4 style="margin-bottom: 0px;">FOGGERS:</h4> Foggers emit water in fine droplets with low flow rates (.8-2 GPH).This makes them ideal for saturating the surface of containers slowly so the water is more evenly absorbed.They are available with a barb,thread or with a small spike assembly.Suggested use is for irrigating containers or baskets.Foggers are also used on patios and around pools to create a cool environment for people or pets to enjoy (look for DIG's Ocean Breeze kits for more information). To install using the 1/2" poly tubing as the mainline,first attach <img src="/images/DS20L/drip_irrigation_beni_216b.gif" alt="" width="153" height="211" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />micro tubing to a barb.Punch a hole in the poly tubing and insert barb. Then run the micro tubing to the plant and cut.Attach the fogger and secure with #67 stake.<img src="/images/DS20L/drip_irrigation_beni_216a.gif" alt="" width="207" height="163" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />To install using the 1/4" micro tubing as the mainline,run the 1/4" micro tubing to the plant,and secure the using #53 1/4" C-clamp.Cut the micro tubing and connect #26 1/4" tee.Run a length of micro tubing into the container.Attach back end of the micro tubing to tee and a fogger in the plant. <h4 style="margin-bottom: 0px;">POP-UP MICRO SPRAYERS:</h4> Many residential landscapes contain locations where the plant material is best irrigated with micro sprinklers or micro sprayers. Although DIG micro sprayers on stakes are not easily seen there may be situations where it would be preferable if the sprayers were concealed, or less visible to the human eye. Consider installing Pop-up micro sprayers on the perimeter of any flowerbed or foot path that contains closely <img src="/images/DS20L/drip_irrigation_beni_216c.gif" alt="" width="290" height="207" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" />spaced annuals, perennials or groundcover. The heads will pop-up 12" and begin spraying only 4&b when the system is running. <br><br> The Pop-up micro sprayers are available in 90°,180°, and 360° pattern. They are easy to install,and connect to the 1/2" poly tubing using the 4(bpreassembled barb. <br><br> First, dig a hole about 10" deep at the headlocation(s), then lay out a length of 1/2" polytubing nearby. Punch a hole in the side of thepoly tubing, and insert the barbed end from thePop-up's micro tubing into the hole. To complete the installation, set the head in the hole about 2-4" above finish grade and backfill. Remove the nozzle and flush the heads thoroughly beforeoperation. <h3 style="margin-bottom: 0px;">Retrofit Products </h3> Conserve water and reduce weeds at the same time! DIG's retrofit drip heads make it easy to convert a 1/2" sprinkler riser to an efficient drip irrigation system. Many residential gardens have existing high flow sprinkler risers in place. The single and multi-outlet drip heads are designed to simply screw onto these risers enableing the connection of 1/4" micro tubing, drip emitters, and soaker hose. Choose from the #85 single outlet, #87 4-outlet, #89 6-outlet, #86 6-outlet adjustable, or Maverick™ 12-outlet drip head. Select the product according to the number of plants needing irrigation, and their water requirements. Remember larger plants need multiple emitters. <h4 style="margin-bottom: 0px;">INSTALLATION:</h4> Remove the existing sprinkler head and open the system valve momentarily to flush out the riser. Screw the multi-outlet drip head onto the riser. Measure the distance from the head to each plant and cut the micro tubing to the correct length for each plant (do not exceed 20' with any single length of micro tubing). Push the end of each micro tubing onto the barbed outlets of the drip head. Secure the end of the each micro tubing near the perimeter of the plant with a #67 stabilizer stake. The micro tubing may be buried or covered with mulch, but the ends should be left open. <br><br> NOTE: If the entire sprinkler system is not being converted, use high flow drippers. Maverick™ and A4 heads are pressure compensating, pressure regulator is not required. <h3 style="margin-bottom: 0px;">Maverick™ 12-Outlet, and Retrofit Installation </h3> If retrofitting a sprinkler riser, depending on the number of plants to be watered, select either a 1-, 4-, 6- or 12-outlet drip head. Each retrofit head provides a specific flow rate to cover all irrigation situations (see pages 8-9 for detailed information). Use with micro tubing extended to the plants. 1/4" soaker hose can also be attached for irrigating plants that are close together. <br> <img src="/images/DS20L/drip_irrigation_beni_223bb.gif" alt="" width="183" height="144" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_223b.gif" alt="" width="183" height="143" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><img src="/images/DS20L/drip_irrigation_beni_223a.gif" alt="" width="183" height="143" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <br clear="right"> <h4 style="margin-bottom: 0px;">MAVERICK™ 12-OUTLET DRIP HEAD:</h4><img src="/images/DS20L/drip_irrigation_beni_223c.gif" alt="" width="167" height="167" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> Use to convert an existing sprinkler riser into a 12-outlet drip system without disturbing the other sprinkler heads along the line. The Maverick is designed to operate with either 1/4-1/8" micro tubing, and has the option of closing off any zones that are not in use. Maverick heads are available in three different flow rates. If combining Mavericks into an existing sprinkler line, use the Hi-Flow 4 GPH model. If replacing all of the sprinkler heads in a line, use the 1-2 GPH models. We always recommend flushing the line before installation. <br clear="right"><img src="/images/DS20L/drip_irrigation_beni_223d.gif" alt="" width="586" height="390" style=" margin: 5px auto 5px auto; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /><br clear="right"> <h3 style="margin-bottom: 0px;">4- and 6-Outlet Drip Head Installation </h3> When converting sprinklers in more compact spaces, less outlets may be needed. In this case consider the 4- and 6-outlet drip heads. With the #86 6-outlet adjustable drip head each outlet is adjustable between 1-20 GPH. The #87 four outlet is preset at 6 GPH per zone. <br><img src="/images/DS20L/drip_irrigation_beni_226b.gif" alt="" width="280" height="218" style="float: right; margin: 5px 13px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_226a.gif" alt="" width="280" height="218" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <br clear="right"> <h3 style="margin-bottom: 0px;">1/2" Riser Adapter (#90) </h3><img src="/images/DS20L/drip_irrigation_beni_226c.gif" alt="" width="280" height="253" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> This attachment enables the attachment of micro tubing to a sprinkler. The micro tubing is perfect for irrigating container plants, groundcover or shrubs that are not covered by the nearby spray head. Any plant that needs supplemental irrigation will benefit from thissystem. The existing spray or Pop-up nozzle can be reconnected to the 1/2" male pipe threads on top, without affecting the sprinkler's 9)performance. <h4 style="margin-bottom: 0px;">INSTALLATION:</h4> Unscrew spray nozzle from topof riser and momentarily open system valve toflush the line. Connect #90 riser adapter to the top of the riser by turning clockwise until hand tight.Reattach the spray head to the top of the riser adapter or replace with a 1/2" FNPT cap. Lay out the1/4" micro tubing from the riser to the plant(s) and cut to the desired length. Push the end of themicro tubing onto the outlet barb on the riser adapter. At the end of the micro tubing, install theappropriate emission device. Do not exceed 35 GPH with this system. </div> 1

<div style="width: 600px; margin: 25px auto 0 auto;"> Before turning the system on for the first time, leave all 1/2" poly tubing ends open and turn the water on and allow it to run freely for a few minutes. This will flush out any dirt that may be in the system. Close the end of the line by using either #55 hose end or #71 end cap. Check to see that the drippers and micro sprinklers are operating correctly and that there are no leaks in the system. If leakage occurs on 1/2" poly tubing at the base of a dripper or micro sprinkler, remove that dripper/micro sprinkler, and insert a #56 goof plug to close the hole and reinsert the dripper or micro sprinkler in a another area. <img src="/images/DS20L/drip_irrigation_beni_227c.gif" alt="" width="183" height="157" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_227b.gif" alt="" width="183" height="157" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_227a.gif" alt="" width="183" height="158" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <br clear="right"> <img src="/images/DS20L/drip_irrigation_beni_228c.gif" alt="" width="183" height="140" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_228b.gif" alt="" width="183" height="140" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <img src="/images/DS20L/drip_irrigation_beni_228a.gif" alt="" width="183" height="140" style="float: right; margin: 5px 0px 5px 10px; border-color: black; border-width: 1px 1px 1px 1px; border-style: solid;" /> <br clear="right"></div> 1

<div style="width: 600px; margin: 25px auto 0 auto;"> <ul class="listspace" style="margin-right: 15px;"> <li>Inspect drippers, micro sprinklers and micro tubing periodically to ensure that the drippers have not clogged and the micro tubing has not moved. </li> <li>Filter screens should be flushed and cleaned at least once a month, depending on water quality. A check of the filter one week after installation should give you an idea on how often to schedule cleaning. </li> <li>Tubing lines should also be flushed periodically. Again, water quality will determine the frequency of flushing.</li> <li>During freezing weather, we recommend draining poly tubing, or rolling it up and storing it.</li> <li>Remove end caps and open hose ends to flush the line once a year.</li> <li>As the landscape matures, you may need to add, change or remove drippers or micro sprinklers. Consult Chart A on page 10 for recommendations. </li> </ul> </div> 1
