Montana water systems track testable devices under state drinking water rules, and utilities in Montana want a report from a certified tester each year.

Long winters with deep frost make freeze protection a big part of backflow prevention here. Ranches with stock tanks and chemical spraying have cross-connections that need RPZs or air gaps. Grizzly Backflow & Plumbing connects Montana owners with testers for cross-connection surveys, RPZ valve testing and backflow enclosure and freeze protection. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Montana.

Talk to a person

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.

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.

How much does backflow testing cost in Montana?

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