Atmospheric Vacuum Breakers

Atmospheric vacuum breakers (AVB) are the simplest design of backflow preventer, and if you have less than six control valves, they are also the least expensive option. Hose-end vacuum breakers attach to the end of your garden hose to prevent running water from re-entering the system.

Aqualine backflow prevention products feature simple designs for easy installation. Our Aqualine products include atmospheric vacuum breakers and hose-end vacuum breakers.
