Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Ohio.

Talk to a person

How often does a backflow preventer need testing in Ohio?

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.

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.

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.

Does my lawn sprinkler system in Ohio need a backflow preventer?

Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.

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.
