Backflow Testing in Eastern Washington and Northern Idaho
Our Liberty Lake office gives us a strong local base for customers who need backflow testing in Spokane, Spokane Valley, Liberty Lake, Post Falls, Coeur d’Alene, and surrounding areas.
Many properties in this region have required backflow prevention assemblies connected to irrigation systems, fire sprinkler systems, commercial buildings, restaurants, medical facilities, apartment communities, municipal systems, and managed properties. These assemblies help protect the public drinking water system by keeping water from flowing backward when pressure changes occur.
If you received a backflow testing notice from your water provider, the next step is straightforward: schedule a certified backflow test, have the assembly tested properly, and make sure the completed report is submitted to the correct water provider or compliance authority.
Certified Backflow Testing handles that process from start to finish.

More Than Annual Backflow Testing
Certified Backflow Testing provides more than annual testing. We also help when assemblies fail, leak, freeze, break, or need to be replaced.
Our services include:
Certified backflow assembly testing
Backflow repair
Backflow replacement
New backflow installation
Retesting after repair
Report submission to water providers
Residential irrigation backflow testing
Commercial backflow testing
HOA and property management support
Multi-site and municipal testing coordination
If another company tested your assembly and it failed, we may still be able to help. Many backflow testers only perform testing and do not handle repairs. Certified Backflow Testing can step in after a failed test to repair, replace, retest, and help submit the required documentation.
Fast Scheduling and Clear Communication
Backflow compliance can feel confusing, especially when a notice arrives with a deadline. Our goal is to make the process simple.
We help customers understand what is required, schedule the test, complete the work, document the results, and help ensure the report is submitted properly. If you have received a final notice, past-due notice, or possible shutoff warning, let us know when you call. Depending on location, route availability, and the type of work needed, next-day service may often be available.
Built for Homeowners, Businesses and Managed Properties
Backflow testing is not one-size-fits-all. A homeowner may need one irrigation assembly tested before a deadline. A restaurant may need testing and repairs completed quickly to stay compliant. An HOA, apartment community, school, municipality, or property management company may need multiple assemblies tested across several locations.
Our Liberty Lake office is positioned to serve all of those customers with the same straightforward approach: certified testing, clear results, repair options when needed, and proper report submission.
