Fire Sprinkler Backflow Testing in Hernando, MS

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.

Grizzly Backflow & Plumbing connects Hernando, MS building owners with testers who handle fire line backflow prevention testing and paperwork. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Fire Sprinkler Backflow Testing in Hernando, MS.

Talk to a person
How often does a backflow preventer need testing in Hernando, MS?
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.
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.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
How much does backflow testing cost in Hernando, MS?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Hernando, MS.
