Double Check Valve Testing in Buffalo, OH

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 Buffalo, OH 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 Buffalo, OH.

Talk to a person
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.
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.
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.
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.
How much does backflow testing cost in Buffalo, OH?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Buffalo, OH.
