Backflow Preventer Testing
California law requires every backflow preventer to be tested annually to ensure it is protecting the city water supply. Our ABPA-certified testers perform the test on site, complete purveyor-ready paperwork, and submit passing results directly to your water purveyor.
What a Backflow Preventer Does — and Why It's Tested
A backflow preventer is a device designed to keep water from flowing in an undesired direction, protecting the main water supply from contaminants. California plumbing codes require them, and purveyors require an annual test to confirm each assembly only allows flow in one direction.
There are four main types: Reduced Pressure Principle (RP) assemblies, Double Check Valve (DC) assemblies, Pressure Vacuum Breakers (PVB), and Spill-Resistant Vacuum Breakers (SVB). Our testers are certified on every style.
What Our Backflow Testing Service Covers
Full differential-pressure test on RP, DC, PVB, and SVB assemblies, performed to the standard your purveyor requires.
Every test is performed by a tester certified by the American Backflow Prevention Association — the gold standard recognized across California.
Passing results are submitted directly to the city or water purveyor, with a copy provided for your records.
If a device fails, we document the exact failure mode on the report so the repair addresses the actual problem.
Our trucks carry common rebuild kits, so most failed devices can be repaired and retested in the same visit.
We track your test date and see you again next year, so compliance never lapses.
