Fire Sprinkler Backflow Testing in Longbranch, WA

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 Longbranch, WA.

Talk to a person
How often does a backflow preventer need testing in Longbranch, WA?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
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 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.
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.
