Washington State requires all backflow prevention assemblies to be installed properly and tested annually.

Backflow assemblies are installed to protect your drinking water from potential sources of contamination. The only way to ensure that they are working properly is to have them tested by a WA State Certified Backflow Assembly Tester.

Please call 425-830-3749 or email (aplusbackflow@hotmail.com) me to schedule a backflow test or if you have any questions about the backflow testing process.
