Fire Sprinkler Backflow Testing in Los Angeles, CA

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 Los Angeles, CA.

Talk to a person
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.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
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.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
