About Grizzly Backflow & Plumbing

Backflow Testing Company in Sandwich, MA Near Me

Massachusetts runs one of the stricter programs in the country. Under MassDEP rules, RPZ and double check assemblies in Sandwich, MA 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 Sandwich, MA 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

Questions Sandwich, MA property owners ask about backflow testing and backflow prevention.

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 is the difference between an RPZ and a double check valve?
Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.
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.
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.
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.
