Pressure Vacuum Breaker Testing and Repair Near You

The pressure vacuum breaker (PVB) is an important component of the irrigation system. It provides protection against backflow or siphoning of water, or in other terms it keeps outside fertilizer and pesticides from contaminating your drinking water.

How does a Pressure Vacuum Breaker work?

A PVB has a check valve and air inlet that vents to the air. The Pressure Vacuum Breaker is installed close to the water source in the water flow before it goes into the sprinkler valves. Your PVB should be installed above the highest point in the system, usually the tallest sprinkler head or the highest slope in yard. The check valve is designed to allow water through and keep the air inlet closed during normal conditions. When the air pressure is greater than the water pressure, the vent will open and close the check valve preventing backflow of water.
