Backflow prevention devices are put in place to protect the clean water supply in both residential and commercial buildings. A licensed plumber will need to test that system once a year to ensure it works properly. The team at Joe Klosterman Plumbing offers this testing for their customers throughout Cincinnati, OH. They’ve shared some information to help you know what’s involved in the testing and why it’s important.

A Plumber’s Guide to Backflow Testing

The Dangers of Backflow

Backflow happens when pressure causes clean water to reverse direction inside the plumbing, pulling non-potable or dirty water into the clean water supply. This then contaminates the clean water, as that non-potable water likely has harmful bacteria or chemicals. Backflow prevention devices are put in place at any cross-connections of potable and non-potable water to stop the non-potable water from cross-contaminating. As long as the prevention device is working properly, you can feel confident that your tap water is safe for drinking and cooking.

What Backflow Testing Involves

During a test, the plumber will turn the shut-off valve for the water downstream of the backflow prevention device. They will hook up testing hoses to the prevention devices to check that the valves will stop water flow as they should. The plumber can then provide documentation stating that the plumbing system passed the test, as proof that you are following municipal codes by getting the annual testing done. If the system fails the test, they will need to diagnose and handle the necessary plumbing repair before providing that documentation.
