Backflow testing FAQs

Questions about backflow testing

Questions Oak Park, MI property owners ask about backflow testing and backflow prevention.

Talk to a person
How often does a backflow preventer need testing in Oak Park, MI?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
Will my water be off during the test?
Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
Who sends the test report to the water utility?
The tester usually files it, either on the utility's paper form or through its online portal. Ask for a copy for your own records.
How much does backflow testing cost in Oak Park, MI?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Oak Park, MI.
