Backflow Prevention FAQs

  • Backflow prevention testing confirms that your backflow prevention device is fully operational. These devices play an important role by preventing wastewater from flowing backward and contaminating the clean water supply.

    During testing, your technician uses gauges to check the pressure in your device. They also check for leaks and confirm that all valves, seals, and other components are functioning properly.

  • Yes. It’s a legal requirement to have backflow prevention devices tested in Michigan. You must have a certified, licensed technician perform the inspection and submit your report. If you fail to comply with regulations, you could face fines and have your water service disconnected.

    To confirm which regulations you must comply with, review your local water authority’s website for guidance. Commercial and residential properties often have different requirements.

  • Commercial backflow prevention devices should be tested annually. Residential devices require testing in accordance with local regulations, typically every 3 to 5 years.

    Additional testing is required after the initial installation, after any repairs, and if the device is moved.

  • Most backflow prevention tests take 20 to 30 minutes. These devices are typically outdoors and easily accessible. You also don’t have to do anything special to prepare.

    Your plumber simply verifies that the device is working as it should. If it’s not, your plumber identifies and schedules the necessary repairs.
