Riser Adapter for Drip and Sprinkler watering allows both irrigation methods to be used at once, covering all plants effectively. Add 1/4 in. drip tubing from the side port of this unique adapter while keeping your sprinkler head or shrub spray in operation. Install it between the 1/2 in. riser and the spray device. Then simply connect 1/4 in. drip tubing to place drippers, bubblers, micro sprays or emitter tubing near other plants you wish to cover with low volume watering.
