Backflow Basics for WTSO Customers

Understanding Backflow

In a water system, consistent pressure ensures water flows correctly through pipes. A sudden pressure change can reverse this flow, causing backflow. During backflow, non-potable water from a private system may flow back into the public water supply, posing a health risk.

What Is a Backflow Prevention Device?

A backflow prevention device is a mechanical unit installed in your water line to maintain one-way flow, preventing backflow and safeguarding the public water supply. It’s placed between the water meter and the first branch of your private plumbing.

Annual Testing Requirement

Your backflow prevention device must be tested yearly by a licensed plumber or certified backflow tester. Test results should be submitted to your local water utility. Devices needing replacement require a permit and must be installed by a licensed plumber or utilities contractor. Repairs, which don’t require a permit, should be handled by a certified backflow repair technician or licensed plumber.
