Double Check Valve Testing in King William, VA

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 King William, VA 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 King William, VA.

Talk to a person
How often does a backflow preventer need testing in King William, VA?
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.
Does my lawn sprinkler system in King William, VA 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.
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.
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 King William, VA?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in King William, VA.
