4 IN SS Reduced Pressure Detector Assembly Backflow Preventer, UL/FM Butterfly Valve Shutoffs, Cubic Feet Meter, Backflow Flood Sensor
This 4 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 N pattern installation. This assembly consists of a stainless steel body with a quick access sleeve, torsion spring check valves, grooved gear operated butterfly valves with tamper switch, test cocks, corrosive resistant bottom mounted pressure relief valve and comes furnished with a cubic foot per minute meter to detect underground leaks and unauthorized water use. This backflow assembly contains a 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.
