Lawn irrigation in Michigan has a short season. PVBs go live in May and must be drained before the first hard freeze, usually by October. Testing has to fall in that window. Older industrial sites need cross-connection surveys. Grizzly Backflow & Plumbing connects Michigan owners with certified testers for irrigation backflow testing, cross-connection surveys and freeze protection. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Michigan.

Talk to a person

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.

Can a backflow preventer freeze?

Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.

What is a cross-connection?

Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.

How much does backflow testing cost in Michigan?

Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Michigan.

Is fire sprinkler backflow testing different?

Yes. Along with the standard check valve test, NFPA 25 calls for an annual forward flow test on fire line backflow assemblies. Results often go to both the water utility and the fire authority.
