Backflow Prevention

Backflow prevention assemblies help protect the public water system from possible contamination from non-potable water sources, such as lawn irrigation, boilers, fire sprinkler systems, wells, pools, hot tubs, commercial equipment, and medical equipment. The State of Oregon requires backflow prevention assemblies on any water service that has the potential to contaminate public drinking water. All backflow prevention assemblies are required to be tested annually by a certified tester. For more information, visit our website at
