Minor backflow repairs
A failed test or a dripping relief valve usually means worn internal parts. We fix that with the manufacturer’s repair kit and retest the assembly.
Signs a backflow preventer needs repair
- It failed its annual test
- Water is dripping or discharging from an RPZ relief valve
- Water is leaking from a PVB bonnet or air inlet
- Low pressure downstream of the device
What we repair
Inside an assembly are check valve discs, springs, seats, O-rings and (on an RPZ) a relief valve diaphragm. Debris from the water line and normal wear can stop them sealing. A minor repair means cleaning or replacing these parts with the manufacturer’s repair kit for that model, then retesting so the passing result can be filed with your water district.
When a device needs replacing
If the body is cracked or frozen, parts aren’t available, or your water district wants a different device type, the assembly has to be replaced. Replacement and new installation usually need a permit and must be done by a licensed plumbing contractor (C-36). We don’t install or replace devices ourselves, but we can refer you to a trusted licensed plumbing contractor, tell you what your district requires, and test the new device once it’s in.
Don’t plug a discharging relief valve or remove a device yourself: both can leave the water supply unprotected.
Repairs are quoted and approved by you before any work is done. If your device just failed its test, tell us what the tester found or book a test and we’ll take it from there.
BackflowCare is not a licensed contractor. We test backflow assemblies and make minor repairs under $1,000 that don’t require a permit. Installing or replacing a backflow preventer requires a licensed plumbing contractor; we can refer you to one we trust.
