The atmospheric vacuum breaker must be installed with the air inlet in a level position. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: \u003cem\u003eNo valve of any type may be installed on the discharge side of an atmospheric vacuum breaker.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAtmospheric 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.
