What is Backflow Preventer Testing?

Backflow Preventer Testing is a certified check that verifies a backflow prevention assembly is installed correctly and operating within specification. In Michigan, assemblies are tested annually by certified testers who are licensed plumbers. Results are documented and submitted to the appropriate authority to keep your site compliant.

Why Backflow Prevention matters

Backflow is the undesirable reversal of the flow of water. It can introduce non-potable, harmful substances into public or private systems and create serious health and safety risks. Annual testing and servicing by industry experts is your best defense against contamination caused by assembly wear or malfunction.

Who is qualified to perform the test

In Michigan, certified backflow testers are licensed plumbers. That means they can legally repair assemblies when needed. Quality outcomes depend on accurate testing, correct documentation, and hands-on experience with a wide range of approved assemblies.

If an assembly does not pass

A failed result does not always mean replacement. The standard process is to diagnose the issue, provide a clear written quote, and schedule a return visit upon approval to complete repairs and retesting.
