Vacuum Breakers
Available25 products
Vacuum breakers are used in high-hazard applications where backsiphoning could result in harmful health hazards contaminating the water supply. They have an air inlet that allows air into the system, breaks the vacuum, and prevents backward siphoning into potable water supplies.
Connection Type
Pressure Vacuum Breakers
Pressure vacuum breakers prevent backsiphoning of contaminated water in continuous pressure applications such as irrigation systems and industrial process water systems. They consist of a check valve, vacuum relief valve, and at least one test cock for easy testing and winterization.

Atmospheric Vacuum Breakers
Atmospheric vacuum breakers (AVBs) prevent backsiphoning of contaminated water into potable water supplies if a pressure loss creates vacuum conditions. Also called anti-siphon vacuum breakers, they have an atmospheric vent that allows air to enter the valve and prevents a siphon from forming during periods of low or no demand. A seal is engaged to close the vent when water is flowing. They are not for use in continuous pressure applications.
