Drip manifolds attach to the top of 1/2-in. male pipe thread (MPT) PVC risers of various lengths and create a simple way to carry water via 1/4-in. drip tubing to trees, shrubs, perennials, or annuals in beds or containers. This makes them excellent as a direct replacement for existing spray heads. Drip manifolds come in a variety of port configurations from one to eight lines, and there is even a version which allows you to run four drip lines and place a shrub head adapter on top of it for unique situations which require both spray and drip. Flow control versions are excellent choices for non-pressure compensating emitters and micro-sprinklers, while non-flow control versions are appropriate for pressure-compensating emitters and emitter tubing. The 1/4-in. barbs on the manifold rotate 360 degrees for ease of insertion and positioning of 1/4-in. drip tubing. On non-culinary secondary water, install a minimum 120-mesh filter or pressure regulator to prevent debris from plugging emitters and micro-sprinklers. For outdoor irrigation use with cold water only.
