Backflow Testing & Certification.
About This Service
California-required annual backflow testing, RP and DC device certification, and assembly repair. We file directly with your water purveyor.
Backflow prevention assemblies stop contaminated water from flowing backward into the public supply. California requires annual testing on every reduced-pressure (RP), double-check (DC), and pressure-vacuum-breaker (PVB) assembly — typically on irrigation systems, fire sprinkler lines, commercial properties, and any cross-connection between potable and non-potable water.
We're certified backflow testers. We test the assembly, document the actual pressure readings (not just pass/fail), file the report directly with your local water purveyor — Cal Water, Golden State Water, or your municipal department — within their required timeline, and repair the assembly when it fails certification. Most failures are worn rubber components in a manufacturer rebuild kit, so a failed test usually becomes a same-visit repair plus retest.
We track your annual due date and reach out 30 days ahead so you never lapse certification. Water purveyors send notices but can issue fines or shut off service for missed deadlines. Most ${'${city.name}' if False else 'South Bay'} backflow assemblies needing annual testing are on commercial properties, irrigation systems for larger residential lots, and any property with a fire sprinkler system.

Step by Step
How It Works
Schedule before deadline
Annual certification is due 12 months from prior test. We track your due date and reach out 30 days ahead so you never lapse.
Test all four conditions
RP and DC assemblies have specific criteria for both check valves, relief valve operation (RP only), and pressure differential. Calibrated test kits, documented readings.
Repair if it fails
Most failures are worn rubber components in manufacturer rebuild kits. We carry common Watts, Wilkins, and Febco kits — failed test usually becomes same-visit repair plus retest.
File the report
Signed test report goes directly to your water purveyor within their required timeline. You get a copy. No follow-up paperwork on your end.
