Double Check Valve Testing in Skipperville, AL

A double check valve assembly, or DCVA, has two independent spring-loaded checks between two resilient-seated shutoffs and four test cocks. It is approved for low-hazard connections, so you see it on many fire lines, apartment services and some irrigation systems.

The tester bleeds and reads each check separately. Each one has to hold a differential of at least 1.0 psid. If a check reads lower, the cause is usually a worn rubber disc, a weak spring or debris across the seat.

Unlike an RPZ, a DCVA can be installed in a pit or vault in many jurisdictions, which brings its own problems. Flooded vaults make test cocks hard to reach and corrode the bolts. Testers often pump the vault before they can start.

Grizzly Backflow & Plumbing connects you with local testers in Skipperville, AL for double check valve testing, report filing with your purveyor and repair if a check fails. Good backflow prevention depends on both checks holding, not one. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Double Check Valve Testing in Skipperville, AL.

Talk to a person
How often does a backflow preventer need testing in Skipperville, AL?
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.
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.
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.
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.
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.
