DIG - Six Zone High Flow Drip Manifold

DIG's Six-Outlet PC Drip Irrigation Manifold is a high flow emission device used to retrofit an existing ½" sprinkler riser into a six outlet drip irrigation system without altering or increasing the flow of the sprinkler system zone. The six-outlet PC drip irrigation manifold with ½" female pipe thread is a pressure compensating head operating at a pressure range of 15-60 PSI with an even flow rate of 6 gallons per hour (GPH) per each outlet. The Six-Outlet PC Drip Irrigation Manifold allows installation flexibility when incorporated into a new system or as a part of a sprinkler system zone. The six-outlet manifold has six rotating barbed elbows outlets that can be connected to a ¼" micro tubing to deliver water under the plant canopy and using stakes to support the micro tubing in place. The six-outlet manifold can also incorporate a ¼" drip line, ¼" soaker hose or drip emitters to a maximum flow of 6 GPH to achieve good root zone coverage of individual plants or groups of plants.

Features:

  • Replacing the sprinkler riser with the six-outlet manifold can lead to water savings of 50% to 70%
  • Can be used to water roses, shrubs, groundcover, and trees
  • Applies water directly to the plant root zone area, leading to less surface evaporation from leaves and soil
  • Eliminates wet walls and discoloration and staining of fences and windows
  • Designed for new and existing landscapes, including oddly shaped areas where a sprinkler head cannot provide good coverage
  • No special tools or glue are needed
  • Barbed elbow outlets allow installation flexibility
  • Pressure compensating feature allows for equal flow rates from each outlet
  • Install above grade, or place below grade in a 6" emitter box
  • Use with any 1/4" micro tubing

Installation suggestions:

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 best method to water, and the flow rate to use. The most suitable uses for a multi-outlet drip irrigation manifold include watering shrubs, trees, roses, pots, or individual plants that can be irrigated more efficiently using a drip irrigation system.

  • DIG recommends placing their six-outlet manifolds in areas where the plants are close to the sprinkler riser you are replacing. Dig also recommends using shorter lengths of micro tubing, trying not to exceed 6 to 8 feet from the riser, to allow for easy maintenance.
  • Make sure that the output of the six outlet drip irrigation manifold is sufficient to cover the plants in the area close to the sprinkler riser.
  • Remove the sprinkler from the riser.
  • Turn the water on to flush the line. Then shut the water off and thread the 6 GPH multi-outlet drip irrigation manifold onto the riser.
  • From the manifold outlets extend 1/4" micro-tubing to the plant areas. At this point you have a number of options:
    • Secure the end of the micro tubing with a stake. This option will allow for a flow of 6 GPH from each outlet used.
    • On the outlet end of the micro tubing, insert a ¼” barb and connect a ¼" drip line or soaker hose and loop it around the plant. This option will provide a larger wetted area under the plant canopy and provide even water distribution from each of the four outlets. This option allows for 5 to 6 feet of drip line or soaker hose per each outlet with 6 GPH.
    • To the end of the micro tubing insert a ¼" tee. From the tee extend additional lengths of micro tubing and insert a PC drip emitter or adjustable drip emitter, with the drip emitters placed under the plant canopy, at the center between the plant trunk and the plant canopy edge.
  • Connect the micro tubing onto the converter barbs, included with each model and insert each barb into one of the open outlets.
  • Turn the water on and check the system, making sure that all outlets are working and the location of each outlet meets your needs.

Note: One of the most common installation errors is using too few, and poorly spaced, 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 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.
