Pressure vacuum breaker assembly definition

Pressure vacuum breaker assembly means a type of cross connection control assembly which consists of an indepen- dently operating internally loaded check valve and an indepen- dently operating loaded air inlet located on the discharge side of the check valve, a tightly closing shut−off valve located at each end of the assembly, and test cocks. The term “pressure vacuum breaker” has the same meaning as pressure vacuum breaker assembly.

Pressure vacuum breaker assembly means a backsiphonage prevention assembly that contains an independently operated, internally loaded check valve; an internally operated air-inlet valve located on the discharge side of the check valve; tightly closing resilient seated shut-off valves on each end of the check valve assembly; and properly located resilient seated test cocks.

Pressure vacuum breaker assembly means an assembly designed to prevent backsiphonage backflow and used for high or low hazard situations, composed of an independently operating, spring-loaded check valve: an independently operating , spring-loaded air-inlet valve; and tightly closing shut-off valves located at each end of the assembly; and fitted with properly located test cocks.
