Do backflow testers work for the City of Ridgefield?

No. Backflow testers are independent private contractors. The City of Ridgefield does not install or test backflow assemblies. The State of Washington requires backflow tests to be performed by Certified Backflow Testers.

Review a list of City Approved and Certified Backflow Testers linked at the top of this page. This list is updated each year and requires testers to provide current year certifications. Tests performed and submitted by someone not on the city's approved and certified backflow testers list will be rejected and considered invalid until that vendor provides the city with their current year state/city approved credentials.
