Backflow testing FAQs

Questions about backflow testing

Questions Wailuku, HI property owners ask about backflow testing and backflow prevention.

Talk to a person
How often does a backflow preventer need testing in Wailuku, HI?
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.
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.
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.
