DIG Inline Drip Emitters offer flexibility and simplify the installation for residential drip irrigation systems. Their rate of flow depends on the inlet pressure; with higher pressure the flow will increase, with lower inlet pressure, it will decrease. The drip emitters’ nominal flow rates are .5 and 1 GPH at 15 PSI. Available in packs of 10 and 25, these emitters are ideal for use with ¼” micro tubing as the main line in pots, baskets, planter boxes, vegetable gardens and for low-pressure gravity feed systems. Install the drip emitters “inline” as needed in any spacing with the 1/4″ micro tubing as the main line

The Inline Button Drip Emitters are useful in small systems and short runs using 1/4″ micro tubing as the main lateral. One of the main features of these drip emitters is their ability to operate under very low pressures and with lower flow rates making them ideal for gravity feed systems.
Install the drip emitters directly into the micro tubing. Within the layout, we strongly suggest that a minimum of two drip emitters should be placed per plant on opposite sides of the plant, under the plant canopy, centered between the plant stem and the outer edge of the plant canopy.
When using single drip emitters, it is important to select the correct flow rate in order to achieve a wetted pattern shape that can cover at least 70% of the plant root zone. In sandy soil or potting soil, water tends to drain quickly (gravitational force) with little lateral movement, so applying a higher flow rate over a given time period will produce a wider pattern. Using .5 GPH drip emitters for one hour will provide a smaller wetted area then using 1 GPH emitters for the same time, due to the soil composition and characteristics.
One of the most common errors in installing drip irrigation is using too few emitters per plant. All too often only a single emitter with preset flow is placed at the base of a newly planted tree, shrub or rose. In clay soils, a single drip emitter can wet a three to four foot diameter; on sandy soils, the same layout using the same drip emitter will only wet an area of a few inches. Because plant roots can grow up to a few feet a year depending on the plant and location, after one year the diameter of the root system would be much larger than the area covered by the one drip emitter. A single drip emitter per tree or shrub could restrict root development as early as the first year after planting if flow is not adjusted or another drip emitter is not added. We highly recommend adding more than one drip emitter per plant, depending on plant size.
If automation is required, use one of DIG’s hose end timers or battery operated controllers. The ideal controller should have flexible scheduling and two to four start times per day for added flexibility.
