This 2 1/2 inch lead free reduced pressure zone (RPZ) assembly backflow preventer is designed to prevent the reverse flow of liquids due to backpressure or backsiphonage, particularly where a potential health hazard exists.
Its compact, modular design facilitates easy maintenance with a single access cover for in-line repairs. This assembly features a short lay length stainless steel body, test cocks, a corrosive-resistant stainless steel bottom-mounted relief valve, and torsion spring check valves.
Flood Sensor Technology
- Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
- When activated through an add-on sensor connection kit, the flood sensor relays a signal that triggers notification of potential flooding to service personnel.
- The add-on sensor connection kit is available for building management systems and cellular communication.
Warning: Without an add-on connection kit, the flood sensor is a passive component that does not communicate with any other device.
