The Drip Store's Six Outlets Adjustable PC Drip Manifold is a high flow emission device used to retrofit an existing ½ inch sprinkler riser into a four outlet drip irrigation system without altering or increasing the flow of the sprinkler system zone. The six outlets adjustable PC Drip Manifolds with ½ inch female pipe thread is a pressure compensating heads with an even flow rate over a wide range of pressure.
The Six Outlets Adjustable PC Drip Manifold allows installation flexibility when incorporated into a new system or as a part of any sprinkler system zone. The Six Outlets Adjustable PC Drip Manifold has six barbed mini ball valve outlets used with ¼ inch micro tubing to deliver water directly to the plant area. The Six Outlets Adjustable PC Drip Manifold can also incorporate ¼ inch drip line or drip emitters to achieve good root zone coverage of individual plants or groups of plants.
The Adjustable Six-Outlet PC Drip Manifold is designed to retrofit a ½ inch sprinkler riser into a drip irrigation system. Retrofitting a conventional sprinkler riser to a water-saving drip irrigation system requires a few simple steps including evaluation of the areas to be watered, selection of the method to water, and the flow rate to use.
The most suitable uses for Adjustable Six-Outlet PC Drip Manifold include watering shrubs, trees, roses, pots, individual plants, or groups of plants that can be irrigated more efficiently using a drip irrigation system.
First, we recommend using the Adjustable Six-Outlet PC Drip Manifold in an area where the plants are close to the sprinkler riser you are replacing, using short lengths of micro tubing, not exceeding 6 to 8 feet from the riser and not exceeding total flow of 20 GPH with all other devices added.
1. Remove the sprinkler from the riser.
2. Turn the water on to flush the line and shut off the water
3. Thread the Adjustable Six-Outlet PC Drip Manifold onto the riser.
4. From the manifold outlets extend 1/4” micro-tubing to the plant areas (model # T040 for 100' and model # T041 for 500' poly or model # T009 for 50’ and T028 for 100’ vinyl)
At this point you have a number of options:
Option 1: Secure the end of the micro tubing with the stake ((model # S003).). This option will allow for a flow of 0 to 20 GPH from each outlet used.
Option 2: To the end of the micro tubing insert a ¼” barb (model # SF001) and connect a 1/4" drip line (model # T052 with .5 GPH drip emitter every 9 inches) and loop it around the plant. This option will provide a larger wetted area under the plant canopy. This option can allow for 5 to 6 feet of drip per each outlet.
Option 3: To the end of the micro tubing insert a ¼ inch tee (model # SF003). From the tee extend an additional length of micro tubing to the plant and insert a PC drip emitter or adjustable drip emitter (models D002 for 2 GPH or D004 for 4 GPH) with the drip emitters placed under the plant canopy, at the center between the plant trunk and the plant canopy edge.
5. Turn the water on and check the system, making sure that all outlets are working and the location of each outlet meets your needs, adjusting the flow on each outlet as needed.
Note: One of the most common installation errors in drip irrigation installation is using too few, and poorly spaced, drip outlets or drip emitters, often only a single emitter or outlet is placed at the base of a newly planted tree or shrub. In clay soils a single drip emitter or outlet can wet three to four feet in diameter; on sandy soils, however, the same layout using the same drip emitter or outlet will only wet an area less than one foot in diameter. Because plant roots can grow a few feet a year depending on the plant and location, after one year the diameter of the root system might exceed the diameter of the watered area. A single emitter or outlet per tree or shrub could therefore restrict root development as early as the first year after planting. For this reason, it is especially important to place additional drip emitters or outlets around each plant, early in the plant's life. To expand the system we highly recommending continuing with the same model flow rate.
