PVB Testing in South Lake Tahoe, CA

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 South Lake Tahoe, CA.

Talk to a person
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.
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
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.
How much does backflow testing cost in South Lake Tahoe, CA?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in South Lake Tahoe, CA.
