A large share of Maine homes use private wells, so many backflow testing jobs in Maine involve commercial buildings and businesses on public water systems regulated by the state's Drinking Water Program.

Frost runs deep, and almost every testable assembly sits indoors. Seasonal businesses that shut down for winter need devices drained and retested when they reopen. Grizzly Backflow & Plumbing connects Maine property owners with testers for commercial backflow testing, backflow enclosure and freeze protection, and test report filing with the water district. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Maine.

Talk to a person

Who is allowed to test my backflow device?

A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.

What happens if I miss the backflow test deadline?

Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.

Why is water dripping from my RPZ relief valve?

A steady drip usually means debris is holding the first check open or the relief valve diaphragm is worn. A cleaning or a rebuild kit fixes most cases.

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.
