Backflow Testing

Backflow Testing for Safer Water

Washington Backflow Assembly Tester Certified

Backflow testing protects your drinking water and the public supply by ensuring your backflow assembly is working properly to prevent contamination from non-potable sources like irrigation systems, sprinklers, or pools. Required annually by Washington state law, we handle the test and submit the results directly to your water provider.

Our Backflow Testing Service Includes:

Inspect the backflow assembly to ensure proper installation
Access flooded or dirt-covered assemblies (additional $5 fee)
Test line pressure to ensure proper operation
Submit compliance documentation for annual certification to your local jurisdiction (additional fees may apply; depending on jurisdiction)
Check all shutoff valves and check valves for leaks or malfunctions
Recommend repairs or replacement, if needed.
