Backflow Testing & Prevention in Bonita, CA

A failed backflow preventer must be repaired or replaced and retested before the certification can be filed. We carry replacement parts for the most common preventer models and can often complete a repair and retest in the same visit. If a replacement assembly is needed, we install a certified unit and complete the retest on the same trip. Your water district typically requires correction within 30 days of a failed test.

Annual backflow preventer testing in San Diego typically costs $75-$150 per assembly for a standard residential double-check or pressure vacuum breaker. If the preventer fails and needs repair, parts and labor add $100-$400 depending on the assembly type and what failed. Full preventer replacement runs $200-$600 installed for a standard residential assembly. Call (858) 925-5546 to schedule your annual test.

Yes. The equestrian and rural-residential properties along Bonita Road and the Lower Sweetwater Valley sometimes still have private well infrastructure that requires regular service. We handle pressure tank replacement, well pump service, sediment filtration, water treatment system installation (softener, iron filter, UV), and the supply-line work that goes with rural property scope. We also handle the larger irrigation supply lines common on multi-acre properties.

Very common at this point. Most original Bonita tract homes from the 1970s-80s were built on slab with copper supply lines beneath. After 40+ years, those copper lines develop pinhole leaks from corrosion and pressure cycling. First signs are usually a warm spot on the floor, an unexplained jump in your water bill, or moisture appearing at a wall edge. We use acoustic and thermal imaging to pinpoint the exact leak location before any concrete is opened.
