Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in North Carolina.

Talk to a person

How often does a backflow preventer need testing in North 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.

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.

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.

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.

How much does backflow testing cost in North Carolina?

Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in North Carolina.
