If a backflow preventer fails its annual test, the certified tester will diagnose the issue — often a worn check valve, damaged disc, or fouled relief valve. Most testers in Santa Monica can repair the device on site and re-test it the same day. Your water authority may require the passing report within a set deadline.
Cross-connection control prevents contaminated water from flowing backwards into the clean water supply. Backflow prevention devices are installed at cross-connection points to protect public health. Regular testing ensures these devices function properly. Many municipalities in California require cross-connection control programs for commercial properties and irrigation systems.
Many municipalities in California require annual backflow testing for commercial and residential properties with backflow prevention devices.
