Watts Lead Free RPZ Backflow Preventer with Strainer, Flood Sensor, 1-1/2 in.

The Watts 88004084 is a 1-1/2 in. reduced pressure zone backflow preventer with a lead free copper silicon alloy body and a built-in strainer. It guards the potable supply against backsiphonage and backpressure at health-hazard cross-connections and service line entrances in continuous pressure piping.

Inside are two independent in-line check valves with captured springs and replaceable seats, plus an internal relief valve that reduces the space the assembly needs. Resilient seated, full port ball valve shutoffs operate with a quarter turn of their tee handles, top mounted test cocks simplify testing, and a single access cover with modular checks allows in-line repair. Connections are NPT.

A flood sensor with SentryPlus Alert technology watches for heavy discharge from the relief valve. With an add-on connection kit for BMS or cellular communication, it can send a flooding alert.
