Backflow Testing in San Diego
San Diego County water districts require annual backflow testing on many residential and commercial properties. We test, report, and repair same day.
San Diego County requires annual backflow prevention testing on irrigation systems connected to the public water supply, commercial properties, and residential properties with special plumbing connections. When your water district sends a testing notice, the testing must be completed by a certified backflow tester and the results filed with the district before the deadline. Plumbing Pro San Diego holds the required backflow certification, tests your preventer on site, files the report directly with your water district, and repairs or replaces failed preventers the same visit. Whether you received a notice from the City of San Diego, Carlsbad, Escondido, or another district, we handle the full process.
