Double Check Valve Testing in Miami, FL

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 Miami, FL 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 Miami, FL.

Talk to a person
What is the difference between an RPZ and a double check valve?
Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.
How long does a backflow test take?
A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.
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.
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.
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.
