1/2" Pressure Compensating Dripline, black

DIG's 1/2" (.600" ID X .700" OD) black dripline has 1-GPH pressure compensating (PC) drip emitters built into the interior wall of the dripline every 12”. Each PC drip emitter consists of a cylinder with a labyrinth water passage, filter and silicon diaphragm. The emitters continuously adjust to varying incoming water pressure ranging from 10 to 45 PSI, ensuring a constant flow rate along the dripline regardless of any elevation along the line. In addition, their self-flushing mode allows particles to pass harmlessly through, providing reliable performance and a longer life.
For commercial and residential applications, install this drip line above the ground and, if desired, cover it with mulch to blend with the landscape. The PC dripline is ideal for plants in preset spacing, narrow plantings, and closely spaced plants in rows, as well as for hedges, groundcover, shrubs and roses. For complete coverage of an area, use multiple lines of dripline, placing the lines 16" to 24" apart. In addition, the dripline can be used around a house foundation to reduce soil movement, cracking and slab damage.

About

DIG’s PC™ Dripline delivers constant deep watering directly to the plant roots. The flow uniformity from each drip emitter provides efficient watering over the length of the dripline. The dripline can be used in a wide range of layouts to accommodate most landscape and garden watering requirements. The 100’ or 500' black coils of dripline have 1 GPH (gallons per hour) pressure compensating inline drip emitters built into the inner side of the dripline every 12”, and can be expanded by connecting the coils together for lengths of up to 330’ @ 45 PSI.
For commercial and residential applications, install the dripline above the ground and, if desired, cover the dripline with mulch to blend with the landscape. The dripline is ideal for plantings in preset spacings, narrow plantings and closely spaced plants in rows, as well as for hedges, groundcover, shrubs and roses. It can also be used around trees, or can be laid around house foundations to reduce soil movement, cracking and slab damage. To protect house foundations in areas with severe weather changes, install the dripline above and on flat ground 4” to 8” from the wall. Keeping the soil at a constant moisture level will help reduce expansion and contraction, which puts stress on foundations.

Installation Recommendations:

Dripline irrigation can be used as part of any drip irrigation installation. It can be extended or connected into the 1/2” drip irrigation tubing using compression fittings with .700 OD, DIG's Nut Lock™ fittings or brown 17-mm barbed fittings.
To install, first review the garden area and make a drawing of the garden or site with your preferred layout of the dripline.

If automation is required, use one of DIG's hose end timers or battery-operated controllers. The ideal irrigation controller should have flexible scheduling and two to four start times per day for added flexibility.

Type of dripline layouts:

  1. Single dripline for narrow plantings.
  2. Multiple lines of dripline for complete coverage of an area with the lines placed 16” to 24” apart.

Installation from a battery-operated controller or 24VAC valve with pipe thread

  1. If the dripline installation is started from a PVC pipe, first shut off the main water supply.
  2. If an automated system is preferred, we recommend installing a 3/4” ball valve or gate valve before the battery operated irrigation controller with a valve or 24VAC valve (if used). This ball valve can be very useful for emergency backup, turning the water off manually. This type of arrangement is used by professional installers.
  3. Turn the water supply on to flush the line and then shut the water supply off using the new ball valve or gate valve.
  4. Install a battery operated controller with a valve, or the 24VAC valve, first wrapping TEFLON tape on all the male thread fittings used.
  5. Turn the water supply on again to pressurize the battery operated controller, or the 24VAC valve. The unit will open momentarily and then will shut off.
  6. Test the battery operated controller with a valve or the 24VAC valve making sure that the unit turns on and off automatically. If using a battery-operated controller, program the controller.
  7. After the battery operated controller with a valve or 24VAC valve, add a 3/4” screen filter with 155-mesh (DIG model # D55). The screen filter is used to protect the dripline from clogging. Next, add a 3/4” preset 25-PSI pressure regulator, heavy-duty pressure regulator (DIG model # D46P or HDPR-25) or adjustable pressure regulator (DIG model # PRV075). The pressure regulator is used to lower the incoming pressure used with drip irrigation and dripline system.
  8. To the pressure regulator, add a 3/4” PVC thread x 3/4” slip adapter and to the PVC adapter connect the PVC pipe. Then lay out the PVC pipe to the area where the dripline is to be installed.
  9. For a single line of dripline, connect a PVC-to-drip coupling (DIG model # D48) to the PVC pipe and connect the dripline to the coupling, then lay it out.
  10. For multiple lines of dripline, at the watering site, add a 3/4” PVC slip tee every 16” to 24" and glue a PVC-to-drip coupling (DIG model # D48) to the tees. To each PVC-to-drip coupling, connect the dripline and lay it out.

Installation from a faucet or hose thread

  1. If an automated system is preferred, install a battery operated hose end timer (DIG model # B09D) or solar powered hose timer (DIG model # EVO100).
  2. Test the hose end timer and make sure that is working correctly, then program the timer.
  3. To the hose end timer, add a backflow device (model D45), then a 25-PSI pressure regulator (model D46) and follow with a 3/4" swivel adapter with a screen (model C34). If water quality is a concern, we highly recommend adding DIG's fine mesh 3/4" filter with 155-mesh (model D57A) after the hose end timer.
  4. Connect an 1/2” poly drip tubing as the main lateral and lay the poly drip tubing to the area where the dripline is to be installed. Secure the 1/2” poly drip tubing to the ground every 6' to 10' using a stake (DIG model # R60).
  5. For a single line of dripline, connect the poly drip tubing to the dripline using a coupling (DIG model # C33) and lay out the dripline.
  6. For multiple lines of dripline, at the watering site, add a 1/2” compression tee every 16” to 24” (DIG model # C35). To each tee, connect the dripline and lay it out.
  7. Turn the water on and flush the dripline.
  8. Turn the water off and close the end of the 1/2” poly drip tubing and dripline using a hose end (DIG model # Q58) or figure “8” (model F68B).
  9. Pressure-test the system to identify leaks in the poly drip tubing, fittings, and dripline.

About the soil and suggested watering intervals:

• Sandy soil or light textured soil: Water percolates straight through before it can spread far enough horizontally, so apply water at close intervals such as every other day for 20 to 40 minutes depending on plant size and type, daylight conditions (full sun, partial sun or shaded), and weather pattern (cold to hot) with the plants under full sun getting the longer period.
• Loamy soil or medium textured soil: This is the ideal soil condition with water moving slowly and spreading evenly, so apply water at wider intervals such as every three to four days for 30 to 50 minutes depending on plant size, type, daylight conditions (full sun, partial sun or shaded), and weather pattern (cold to hot) with the plants under full sun getting the longer period.
• Clay soil or heavy textured soil: Water is absorbed very slowly, so apply water at longer intervals such as every four to five days for 30 to 40 minutes depending on flow rate, plant size and type, daylight conditions (full sun, partial sun or shaded), and weather pattern (cold to hot) with the plants under full sun getting the longer period.
