Pressure Vacuum Breaker
Description of the PVB Backflow Device
Backflow device configured with a spring-loaded float and an independent spring loaded check valve. Check valve that is designed to close with the aid of a spring when flow stops. It also has an air inlet valve that is designed to open when the internal pressure is one psi above atmospheric pressure so that no non-potable liquid may be siphoned back into the potable water system. Being spring -loaded it does not rely upon gravity, as does the atmospheric vacuum breaker. This assembly includes resilient seated shut-off valves and test cocks. The PVB must be installed at least twelve (12) inches above all downstream piping and outlets. The PVB may be used to protect against a pollutant or contaminant; however, it may only be used to protect against backsiphonage. It is not acceptable protection against backpressure.
