Prevent Dangerous Backflow
Do you own an irrigation system, fire sprinkler system, or lake water pumping system? Washington State law requires that backflow assembly devices be installed in these types of plumbing conditions.
What Is Backflow?
It's exactly what it sounds like: the water is flowing in the opposite direction from its normal flow. With the direction of flow reversed, due to a change in water pressure, backflow can allow contaminants such as fertilizers, garden chemicals, insects, and pet waste to enter your drinking water system.
A backflow prevention assembly ensures water flows only one way. If you have any of the above systems, but did not receive a reminder notice from the city about annual testing, please contact our Water Quality Group at
