DIG’s Adjustable Six-Outlet PC Drip Manifold (1/2″ female pipe thread) is used to retrofit an existing 1/2” sprinkler riser into a six-outlet drip irrigation system without altering or increasing the total flow of the sprinkler system zone. It has six independently adjustable, pressure compensating outlets with flow rates between 0 and 20 GPH at operating pressures of up to 50 PSI. The manifold’s six rotating 1/4” barbed outlets have flow control knobs which offer installation flexibility when the unit is incorporated into a new system or when replacing any of the sprinkler heads in a zone. Each outlet accepts 1/4″ micro tubing, 1/4” soaker hose or the addition of drip emitters and adjustable stakes to bring water to each plant root zone at a maximum flow of 20 GPH per outlet.

The AD6 Adjustable Six-Outlet PC Drip Manifold is utilized on new or existing installations to retrofit a sprinkler riser into a drip irrigation system, applying 50% to 70% less water than a conventional sprinkler system by applying the water directly to the plant roots. It has six outlets with individual adjustable flow controls with a range of 0 to 20 GPH. The manifold offers greater installation flexibility by allowing incorporation of 1/4” drip line, 1/4” soaker hose or the use of drip emitters to a maximum flow of 20 GPH per outlet. It can be used to cover individual plants or closely spaced groups of plants within the layout.
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 selection of the flow rate. The most suitable uses for a drip system include watering shrubs, trees, roses, pots, individual plants or groups of plants that can be irrigated more efficiently using a drip irrigation system.
a. Secure the end of the micro tubing with a stake (model P35B, pack of 10). This option will allow for a flow of 0 to 20 GPH from each outlet used.
b. To the end of the micro tubing, insert a 1/4” barb (model H80A, pack of 5), connect 1/4″ dripline (.5 GPH drip emitter every 9″ or 12″) or soaker hose (model PSH50 porous 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 six outlets.
c. To the end of the micro tubing, insert a 1/4” tee (model H82A, pack of 5). From the tee, extend additional lengths of micro tubing and insert a 4-GPH PC drip emitter or adjustable drip emitter (models B224B, pack of 10 or B10B, pack of 10) with the drip emitters placed under the
plant canopy, at the center between the plant trunk and the plant canopy edge.
