Backflow Testing in Metro Detroit
Backflow prevention protects your drinking water from contamination. When water pressure changes (from a main break, hydrant use, high-demand events, or cross-connection issues), contaminated water can be pulled backward into the clean supply. A backflow preventer is designed to stop that, but it must be tested periodically to confirm it is working properly.
A-Fordable Plumbing & Mechanical provides professional backflow testing for homes and businesses across Metro Detroit. If you have a required annual test, need documentation for compliance, or want to confirm your system is protecting your water supply, our team can help.

What Is Backflow?
Backflow is the unwanted reversal of water flow. Instead of clean water moving toward fixtures and appliances, water can flow the opposite direction and bring contaminants into the potable supply. Backflow typically happens when pressure changes in the system.
Two common causes of backflow
- Backsiphonage: a drop in supply pressure pulls water backward
- Backpressure: downstream pressure becomes higher than supply pressure
A properly installed backflow preventer helps protect your water, but testing is what confirms the device is operating as intended.
Who Typically Needs Backflow Testing?
Many properties need testing due to a required backflow preventer or a potential cross-connection. If you received a notice for testing or you have a backflow device on-site, it is a good idea to schedule service before deadlines.
- Commercial buildings with backflow prevention requirements
- Restaurants, medical offices, and facilities with specialized equipment
- Multi-unit properties and mixed-use buildings
- Irrigation and sprinkler systems (a common source of cross-connection risk)
- Boiler systems and certain process equipment
- Properties with fire suppression systems that require backflow protection

When Should You Schedule Backflow Testing?

- You received a city or water authority notice requiring a test
- You need annual certification for a commercial property
- You recently installed a sprinkler system or made plumbing changes
- You are buying or selling a property and need verification
- You suspect a backflow preventer is not functioning correctly
