Backflow Repair & Replacement
Failed a test? A licensed journeyman plumber can rebuild or replace your assembly — and re-test it compliant.
When an assembly fails — a check valve won't hold, a relief valve weeps, or a device is simply worn out — it has to be repaired or replaced before it can pass. Most testers on the island stop here and hand you a failure notice to shop around with. We don't.
Because we're a licensed journeyman plumber and certified cross-connection specialist, we diagnose the failure and make the fix ourselves. That means one visit, one bill, and no weeks stuck out of compliance while you chase down a separate contractor.
We'll show you exactly what failed and why, quote the repair or replacement clearly before any work, and re-test once it's done — so you finish with a passing, compliant assembly and a report filed with the County.
