PVB Testing in Bean Station, TN

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 Bean Station, TN.

Talk to a person
How often does a backflow preventer need testing in Bean Station, TN?
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.
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.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
