Backflows


Used on high hazard applications, The Reduced Pressure Zone Backflow Assembly (RPZ or RP) protects against both backpressure and back-siphonage and is considered the best mechanical backflow protector available out on the market today. It consists of two independently acting spring loaded check valves with a reduced pressure zone between the checks that will open to atmosphere should the pressure fall. (ASSE 1013 or 1047)
