Fire Sprinkler Backflow Testing in Eden Prairie, MN

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 Eden Prairie, MN.

Talk to a person
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.
Does my lawn sprinkler system in Eden Prairie, MN need a backflow preventer?
Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.
What does a failed backflow test mean?
A check valve or the relief valve did not hold its required pressure differential. The device needs repair or replacement, then a retest before a passing report can be filed.
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
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.
