What to Do After a Failed Backflow Test

Receiving a failed backflow test result can be stressful, but the process is straightforward if you act promptly. Here’s what to do.

Step 1: Understand What Failed

Your certified tester’s report will specify which component failed (check valve #1, check valve #2, relief valve, etc.) and the measured values. Ask your tester to explain the failure if it’s not clear.

Step 2: Hire a Licensed Plumber to Repair or Replace the Device

A backflow prevention assembly repair or replacement must be performed by a licensed plumber (not just a tester). The plumber will either rebuild the assembly with new components or replace the entire device.

Step 3: Have the Device Re-Tested

After repair or replacement, a certified tester must re-test the assembly and produce a passing test report. Some certified testers are also licensed plumbers and can perform both services.

Step 4: Submit the Passing Report

The passing re-test report must be submitted to your water utility within their required timeframe. Confirm submission with your tester.

Step 5: Keep Records

Keep copies of all test reports — both the failed test and the passing re-test. Most utilities require records to be maintained for a minimum of 3 years.
