Atmospheric Vacuum Breakers (AVB)
Atmospheric vacuum breakers (AVB) are the simplest design of backflow preventer. If you have less than six control valves, they are the least expensive. These devices are not designed as a whole-system backflow prevention valve; one must be installed at every control valve. Sprinkler Warehouse does not recommend AVB’s for irrigations systems where there is a potential to contaminate drinking water.
