Typical Installation
An Atmospheric Vacuum Breaker may be used to protect a crossconnection against backsiphonage, where the vacuum breaker is not subjected to back pressures due to pumps or any other conditions which may cause backpressure, no matter how slight. It must be installed on the discharge side of the last shutoff valve. Code requirements vary as to the height this vacuum breaker must be installed above the highest overflow level but a minimum of 6" (150mm) is required. The atmospheric vacuum breaker must be installed with the air inlet in a level position.
Note: No valve of any type may be installed on the discharge side of an atmospheric vacuum breaker. Unit cannot have any shutoff downstream of it.
Operation
FEBCO Series 710 assures positive protection against backsiphonage of impure water into the main supply in the event that pressure loss causes vacuum conditions. A poppet seals the air inlet when the unit is pressurized. When a backsiphonage occurs, the poppet drops to allow air to enter the downstream piping. At the same time the poppet shields the water inlet to prevent foreign materials from entering the upstream piping. Restoration of pressure (flow) lifts the poppet to seal the air inlet.
Specifications
Atmospheric Vacuum Breakers shall be installed on the discharge side of the last shutoff valve, shall have all bronze bodies and bonnets, and shall be of the non-spilling type. Vacuum breaker shall be rated to 150psi (10.3 bar) working pressure and shall withstand water temperatures of 32ºF to 110ºF (0ºC - 43ºC) for the Series 710.
