Standard 2" Backflow Preventer

Designed to give maximum protection against backflow caused by 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).

Consists of two spring-loaded poppet type valves and a mechanically independent, hydraulically dependent pressure differential relief valve.

Three top mounted test cocks ensure easy access during repair and maintenance when unit is installed in tight places.
