Watts RPZ Backflow Preventer with Strainer and Flood Sensor - 88004040

The Watts 88004040 is a reduced pressure zone backflow preventer with a lead free copper silicon alloy body and a built-in strainer. It keeps contaminated water out of the potable supply during backsiphonage or backpressure at health-hazard cross-connections and service line entrances.

Two independent in-line check valves with captured springs and replaceable seats work with 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, test cocks are mounted on top, and a single access cover over 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.
