Backflow is the undesirable reversal of water in a customers water system back into the city water supply. Once the water passes through your meter, the city doesn't want it back.
A backflow preventer is a mechanical device, containing check valves that close when the pressure in the city water supply drops, thus preventing the reversal of water.
The state of California, per Title 17, requires an annual test of all backflow preventers by an A.W.W.A certified tester. Any structure built after 1987 must have a backflow preventer.
We test all sizes, types and locations of backflow preventers. From 1/2" devices up to 10" monsters, we get them all certified in Napa, Saint Helena and American Canyon.
