Reduced pressure principle backflow preventer is designed to give maximum protection against backflow caused by either back-pressure or back-siphonage from a cross-connection wherein a contaminant hazard exists (i.e. a health hazard), or a pollutant hazard exists. The assembly is composed of two spring-loaded poppet type check valves and a mechanically independent, hydraulically dependent pressure differential relief valve. Three of the testcocks are mounted at the top to assure easy access during repair and maintenance when unit is installed in tight places.
Note: You can create a Fire Hydrant Backflow Preventer by using a RSMSA25F20T and a DMH2025F.
