What to Expect on Test Day
Your tester arrives, locates your backflow assembly (typically near the water meter or service entrance), and connects calibrated differential pressure gauges to the test cocks. Water shuts off for 15–30 minutes during testing. You receive a signed test report immediately. Pass: results are filed with your utility. Fail: the tester identifies the fault and repairs or returns within the required compliance window. Always confirm your tester files results with your utility — request confirmation before they leave.
