The non PC model D051, .5-GPH and D052, 1-GPH are in-line drip emitters with 1/4" barb inlet and outlet. They are suitable for use in planter boxes, containers and with vegetable planters. Use this drip emitter with 1/4" micro tubing as the main line and install the emitter where required.
The inline drip emitter perform perfectly well in a short run only, try not to place the emitters closer than 6 inches apart. The inline drip emitter with 1/4 inch barbed inlet and outlet provide flexibility and simplify the installation and customization of residential drip irrigation systems. Suitable for plants and/or trees in containers or in the ground, these non-pressure compensating drippers’ rate of flow depends on the inlet pressure; with higher pressure the flow will increase, with lower inlet pressure, less flow will occur. The Inline Button Drip Emitters’ nominal flow rates are .5 and 1 GPH at 20 PSI. The Inline Barbed Drip Emitters are ideal for use in pots, baskets, planter boxes; in systems with short runs and low pressure gravity feed systems. Install the drip emitters into the ¼ inch micro tubing.
The Inline Button Drip Emitters are useful in small systems and short runs using the ¼ inch micro tubing as the main lateral. One of the main features of this drip emitter is its ability to operate under very low pressures and with lower flow rates making it 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.
One of the most common errors in installing drip irrigation is using too few emitters per plant, poorly spaced. 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 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. DIG highly recommends adding more than one drip emitter per plant, depending on plant size.
If automation is required, use one of our hose end timers or battery operated controllers.
Step 1. Using the drip tubing as the main lateral or as a sub lateral, lay out the drip tubing per your layout drawing. Secure the drip tubing to the ground using stakes (model S006 or S008) in key areas and add more stakes as you unroll the drip tubing. Add stakes every 10-12 feet and at the end of each section or as needed. An extra 1% of drip tubing length should be added to each lateral to compensate for contraction at low temperature.
Step 2. Throughout the installation and per your drawing layout, add [if needed] ½ inch fittings, such as tees (model LF005) and elbows (model LF007), leaving the end of the drip tubing open. To install the 1/2 inch compression drip fittings, cut the drip tubing with a hand pruner, being careful to keep dirt from entering the line. Hold the fitting in one hand and the drip tubing in the other and force the drip tubing into the compression fitting by moving it from side to side.
Step 3. The drip emitters are installed along the micro tubing at varying or at specific intervals. The distribution uniformity of water from the drip emitters along the line depends on the incoming pressure, number of drip emitters used per lateral, and the length of the laterals. Special care should be taken to ensure high uniformity of water along the laterals by not exceeding the product recommendations (see Product Specifications).
Step 4. To install the inline drip emitters, follow the steps below:
