What is a pressure vacuum breaker, and how does it work?

A pressure vacuum breaker (PVB) is a backflow prevention device designed to protect your water supply from contamination. It works by maintaining a constant pressure in your sprinkler system, ensuring that water flows in only one direction. If the water pressure drops unexpectedly, the PVB prevents contaminated water from flowing back into your home’s water supply.
