PVB Testing in Knob Lick, KY

The pressure vacuum breaker, or PVB, is the brass device sticking out of the ground near your sprinkler system with a bonnet on top and two small test cocks. It is the most common backflow preventer on residential irrigation.

A PVB test checks two things. The air inlet has to open when pressure in the body drops to about 1.0 psi. The check valve has to hold at least 1.0 psid in the direction of flow.

The usual failures are a cracked bonnet from a freeze, a stuck poppet, or a check that leaks because the rubber has gone hard after years in the sun. Water spitting out from under the canopy when the system starts is a sign the poppet is not seating.

A PVB must sit at least 12 inches above the highest sprinkler head it serves. If yours is lower, it may not pass inspection even with good readings.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about PVB Testing in Knob Lick, KY.

Talk to a person
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.
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.
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.
Who sends the test report to the water utility?
The tester usually files it, either on the utility's paper form or through its online portal. Ask for a copy for your own records.
How much does backflow testing cost in Knob Lick, KY?
