Backflow Prevention & Testing

If your San Diego property has a fire sprinkler system, irrigation connection, or commercial water service, you're required to have your backflow prevention device tested annually by a certified tester — and the county will send you a notice if you fall behind. Our team tests RPZ valves, double check valve assemblies, and atmospheric vacuum breakers, then files the certification report directly with the City of San Diego or your local water district. If your device fails the test, we repair or replace it on the spot so you don't need a second appointment.

What We Do

• Annual backflow testing and certification with same-day report filing
• RPZ (reduced pressure zone) and DCVA (double check valve assembly) testing
• Failed device repair and replacement during the same service visit
• New backflow preventer installation for irrigation, fire, and commercial systems
• Compliance reporting filed directly with City of San Diego and local water districts
• Multi-property and HOA testing programs for condo buildings in downtown, UTC, and Hillcrest
