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.
