A Pressure Vacuum Breaker (PVB) is an important device in irrigation systems that prevents contaminated water from flowing back into the clean water supply. It keeps your drinking water safe from harmful substances like garden chemicals by maintaining constant pressure and breaking the vacuum during backflow conditions. PVBs are typically installed above ground and are known for their durability, easy maintenance, and cost-effectiveness, making them a smart choice for both residential and commercial irrigation systems.
