How Pressure Vacuum Breakers Work

The PVB is typically installed above ground for irrigation systems, sprinkler systems, and other outdoor plumbing setups with high risk of backflow. Under normal conditions, water flows through the PVB, with the check valve allowing the flow to move in one direction only. If a pressure drop occurs, the check valve prevents contaminated water from flowing back into the main water supply. This effectively prevents the contamination of a water system from external sources.

Pressure Vacuum Breaker FAQs

What are some common applications for a PVB backflow preventer?

PVBs are often used in outdoor settings to prevent contamination in systems that are connected to other water supplies. You’ll often find a PVB assembly attached to irrigation systems, gardens, landscape watering systems, fountains, and other outdoor water features.

Where should a PVB be installed?

PVBs should be installed about 12 inches above the highest point in the system they protect, typically above ground level. This height allows the device to function correctly by preventing back-siphonage. The PVB valve should also be easily accessible in case of emergencies.

How do I know if my PVB needs maintenance or repair?

PVBs can fail due to wear, debris, or freezing temperatures. Sediment and buildup can cause the internal components to stick or wear out, while freezing can crack the assembly, leading to leaks. Consider applying for an annual inspection and maintenance to ensure that your backflow preventer functions properly.
