Some jurisdictions require the property owner to submit reports, while others accept direct submissions from the tester.

If a backflow preventer fails its annual test, the certified tester will diagnose the issue — often a worn check valve, damaged disc, or fouled relief valve. Most testers in Princeton can repair the device on site and re-test it the same day. Your water authority may require the passing report within a set deadline.

Cross-connection control prevents contaminated water from flowing backwards into the clean water supply. Backflow prevention devices are installed at cross-connection points to protect public health.
