What is backflow testing?
What is backflow testing? It is the certified performance check that confirms a backflow prevention assembly is working correctly and keeping non-potable water out of potable lines. In Michigan, most commercial properties and many residential systems are required to complete What is backflow testing? on a yearly cycle to stay compliant with local authorities and protect public health. This guide explains how it works, what to expect on the day of service, and how Backflow Prevention Services supports you from scheduling to certification.
Why backflow testing matters
A backflow prevention assembly is designed to allow water to move in one direction only. Pressure changes caused by events like water main breaks or pump activity can try to reverse that flow. Annual testing confirms the internal checks and relief mechanisms still operate within specifications.
What is included in a compliant test
- Verification of make, model, size, serial number and installation orientation
- Gauge setup and step-by-step ASSE 5110 testing procedures
- Recording differential pressure readings and pass or fail status
- Documentation for your files and submission to the authority having jurisdiction
Michigan requirements you should know
- Most jurisdictions require an annual test for each installed assembly
- Testing must be performed by a certified tester
- In Michigan, certified backflow testers are licensed plumbers, which means they can legally repair. Scope and quality still depend on training and experience.
