Water Backflow Prevention
The purpose of a backflow prevention device is to keep unsafe drinking water from mixing with the potable water supply. A backflow prevention device must be installed on all residential irrigation systems, fire sprinkler systems, commercial facilities where chemicals are used, boiler systems, and other systems where drinking water could become contaminated.
The State of California requires that all backflow prevention devices, with the exception of atmospheric vacuum breakers, be tested annually by a certified backflow prevention devise tester. This testing process helps ensure a safe drinking water supply for theÂ residents of Ventura County.
