DIG Flag Drip Emitters have a unique style that includes a barbed outlet to extend a 1/4″ micro tubing to the plant area. They are available with a flow of 1, 2 and 4 GPH and an operating pressure range of 10 to 25 PSI (the higher the pressure, the higher the flow). The flag drip emitters are available in packs of 5, 25 and 100, each with a 1/4″ self-tapping barbed inlet and barbed outlet. The flag drip emitter’s two-piece construction allows it to be taken apart for cleaning, by twisting the flag part counter clockwise and pulling it apart. Use for an individual plant, planter boxes, small to large pots, groundcovers, shrubs and trees on short runs, level terrain or low-pressure gravity feed drip irrigation installations.

The 1, 2 and 4 GPH Flag Drip Emitters consist of two parts, the top flag (wing) insert with a large spiral water passage that can be twisted to open and remove for cleaning, and the body. The large-water-path design allows particles to pass through the drip emitter’s water passage, providing reliable performance and a longer life. 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. The three models have preset flows of 1, 2 or 4 GPH at a nominal pressure of 15 PSI and can operate under a pressure range of 5 to 25 PSI.
The emitters may be installed using one of three methods; either directly into the drip tubing, into the drip tubing and extended with micro tubing to the plant and secured to the ground with stabilizer stake or at the end of the micro tubing. Within the layout, we highly suggest that a minimum of two drip emitters should be placed on opposite sides, under the plant canopy, centered between the plant trunk and the plant canopy edge.
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, 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 characteristics.
One of the most common installation errors in installing drip irrigation is using too few emitters. All too often only a single emitter with preset flow is placed at the base of a newly planted tree, shrub or roses. 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 few inches only. Given the fact that 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 a drip emitter is not added. We highly recommend adding more than one drip emitter per plant, depending on plant size.
Basic installation recommendations for this product include first reviewing the area and then making a drawing of the garden or site with your preferred layout. 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.
Recommendations: Wrap all male pipe thread fittings with Teflon tape. Do not use pipe cement on the valve as it will damage the valve and void the warranty.
