Reduced pressure backflow assembly (RPBA definition

Reduced pressure backflow assembly (RPBA means an assembly which is normally used in locations where an approved air gap is impractical. The assembly is effective against backflow caused by backpressure and backsiphonage, and is used to protect the potable water system from substances that constitute a high hazard.

Reduced pressure backflow assembly (RPBA means a state approved backflow prevention assembly composed of two independently acting check valves spring loaded to the closed position and an automatically opening differential relief valve located between the two check valves. Installed as a unit with, and between, two resilient seated shutoff valves and having four properly located resilient seated test cocks.
