Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in South Carolina.

Talk to a person

How often does a backflow preventer need testing in South Carolina?

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.

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.

Will my water be off during the test?

Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.

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.

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.
