Backflow Testing FAQ

Backflow testing is a process used to verify that a backflow prevention assembly is functioning correctly. These devices protect the public drinking water supply by preventing contaminated water from flowing backward into clean water lines. Certified testers use specialized gauges to test the valves and internal components of the device to ensure it meets local water authority requirements.

Backflow testing must be performed by a certified backflow prevention assembly tester who has completed approved training and holds current certification. Many water authorities require that testers use calibrated testing equipment and submit test reports to the local jurisdiction.

Backflow devices protect your drinking water from contamination caused by irrigation systems, chemicals, and cross-connections. ​ If a device fails, polluted water can enter the clean water supply. Annual testing ensures your system is working properly and keeps you in compliance with your local water department.

If you receive a notice from your water provider requiring backflow testing, it means your backflow prevention assembly must be inspected by a certified tester. These notices are part of cross-connection control programs designed to protect public drinking water systems.   For a detailed explanation of why these notices are sent and how to complete the required testing, visit our guide:   Received a Backflow Testing Notice in Colorado?

Most water providers require backflow prevention assemblies to be tested once per year by a certified tester. Annual testing helps verify that the device is working properly and continues to protect the public water system from contamination.

In most cases, a backflow test takes 15–30 minutes depending on the type and location of the device. The tester will connect a calibrated test kit to the backflow preventer and measure pressure differences across the internal valves to verify proper operation.

If a backflow prevention assembly fails testing, it typically means that one or more internal check valves are not sealing properly. Many failures can be corrected through repair and replacement of worn internal components. After repairs are completed, the device is retested to confirm it meets required standards.

No. Backflow prevention assemblies must be installed or removed by a licensed plumber. Certified backflow testers are authorized to perform testing and certain internal repairs, but they are not permitted to install or replace an entire assembly. If a backflow device needs to be replaced, a licensed plumber must perform the installation before the assembly can be tested and certified.

Many irrigation and sprinkler systems require a backflow prevention assembly to protect the public water supply from contamination. These devices are commonly installed on irrigation systems and may require annual testing depending on local water authority regulations.

The short answer is no. We know schedules can be busy. You don’t need to be home—as long as we have access to the backflow device and any required gate or lockbox codes, we’ve got it covered.

Yes — I am certified and registered with the State of Colorado to perform fire suppression backflow testing. I test both residential and commercial fire sprinkler systems and ensure all results are properly documented and submitted to the appropriate local water authority. If your system is monitored, it will need to be placed in test mode during the inspection. If you provide your monitoring company’s contact information, I can coordinate that for you to make the process simple and hassle-free.
