Backflow Prevention & Testing

Backflow Prevention Assemblies require annual mandatory testing and is subject to local and state codes. A backflow assembly is what prevents the water in your system from flowing back into the public water system. The State of Washington Department of Health requires that your backflow assembly be tested annually to insure the safety of our drinking water.

Why do I need my backflow assembly tested? It's because backflow prevention devices have parts that can break down and wear out. By having the test annually, you will help to ensure the drinking water supplied to your home and community remains safe.
