Backflow Preventer
Large Diameter Hose Roller
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 (i.e. a non-hazard).
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.
•The backflow preventer meets the requirements of the following standards:
USC’s FCCC & HR Manual, Sec. 10, ASSE 1015, AWWA C-510 and CSA B64.4.
