Virginia water systems run cross-connection programs under state health department rules, and utilities in Virginia send notices for each testable device.

Northern Virginia suburbs have heavy irrigation and many commercial buildings with fire lines. Winters freeze regularly, and the coast deals with salt air. Grizzly Backflow & Plumbing connects Virginia property owners with certified testers for annual backflow testing, fire sprinkler backflow testing and PVB testing. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Virginia.

Talk to a person

How often does a backflow preventer need testing in Virginia?

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.

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 happens if I miss the backflow test deadline?

Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.

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 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.
