Fire Sprinkler Backflow Testing in South Walpole, MA

Fire lines usually carry a double check detector assembly (DCDA) or a reduced pressure detector assembly (RPDA). The bypass meter on the side catches small leaks or unauthorized use without slowing water during a fire.

Fire sprinkler backflow testing has two jobs. The backflow test checks each valve against its required differential, like any other assembly. NFPA 25 also calls for an annual forward flow test at system demand, which proves the assembly will pass the water the sprinklers need.

Assemblies on fire lines are often 4 to 10 inches, and many sit in vaults or riser rooms. Shutting one down takes coordination, because the building is without sprinkler protection during the test. Building owners usually notify the alarm monitoring company before work starts.

The report often goes to two places: the water purveyor and the local fire authority.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Fire Sprinkler Backflow Testing in South Walpole, MA.

Talk to a person
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.
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.
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.
Who sends the test report to the water utility?
The tester usually files it, either on the utility's paper form or through its online portal. Ask for a copy for your own records.
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.
