Massachusetts runs one of the stricter programs in the country. Under MassDEP rules, RPZ and double check assemblies in Massachusetts are tested more often than the once-a-year schedule common in other states.

That means more visits, more reports and more chances for a missed deadline. Older buildings with deep basements hold most devices, and winter freeze risk keeps them indoors. Grizzly Backflow & Plumbing connects Massachusetts property owners with certified testers for RPZ valve testing, double check valve testing and test report filing on the state schedule. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Massachusetts.

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.

How long does a backflow test take?

A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.

Does my lawn sprinkler system in Massachusetts need a backflow preventer?

Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.

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.

How much does backflow testing cost in Massachusetts?

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