PVB Testing in Saint David, ME

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 Saint David, ME.

Talk to a person
How often does a backflow preventer need testing in Saint David, ME?
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 happens if I miss the backflow test deadline?
Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.
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.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
