8 IN Lead Free Reduced Pressure Detector Backflow Preventer Assembly, OSY Shutoff Valves, Less Meter, Backflow Flood Sensor
This 8 inch reduced pressure detector backflow preventer assembly help stop the reverse flow of liquids due to backpressure or backsiphonage, where potential health hazard exists. Extremely compact and lighter than traditional designs it is approved for horizontal installation. This assembly without a meter bypass consists of a stainless steel body with a quick access sleeve, torsion spring check valves, resilient seated gate valves with outside stem and yoke, test cocks, and a corrosive resistant bottom mounted pressure relief valve. This backflow assembly contains an integrated flood sensor with SentryPlus Alert(R) 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.
