Find a Certified Tester Near You
Seattle property owners with irrigation systems, commercial connections, or fire suppression lines are required to test backflow prevention assemblies annually under Washington's cross-connection control rule (WAC 246-290-490), enforced locally by Seattle Public Utilities. With one of the densest urban cores in the Pacific Northwest and thousands of multi-family and commercial buildings, Seattle runs one of the state's most active backflow compliance programs.
Why Backflow Testing Is a Year-Round Need in Seattle
Seattle’s mix of older buildings in neighborhoods like Ballard and Capitol Hill alongside new high-rise construction downtown means assemblies range from older double check valves to modern reduced pressure assemblies. A certified tester will identify your device, confirm it meets current performance standards, and submit results directly to Seattle Public Utilities to keep your account in compliance.
