The 3-in-1 is a combination filter, pressure regulator, and drip adapter for micro watering applications where clean water and low pressure are important for optimum performance. It connects to a 1-in. female pipe thread (FPT) automatic irrigation valve to form what is called a “drip control zone.” It is compact enough to fit four valves side-by-side in a standard rectangular valve box using a manifold. The filter is made from fine 120-mesh stainless steel and has a flush port on the top for easy cleaning. The compact pressure regulator reduces pressure to 30 PSI while maintaining flow up to 5 gallons per minute (GPM). Both the inlet and outlet are 1-in. male pipe thread (MPT). The Drip-Lock adapter connects to 17mm or .700-in. drip blank distribution tubing. The 3-in-1 is compatible with valves from Orbit, Hydro-Rain, and other major brands. We recommend B-hyve controllers for optimum water conservation. For outdoor irrigation use with cold water only.
