The Best Pressure Vacuum Breaker
A Brief Overview of Pressure Vacuum Breaker
The Pressure Vacuum Breaker (PVB) is a device that prevents backflow of contaminated water from irrigation systems into the main water supply. The PVB is installed at the highest point on the irrigation system, and it works by creating a barrier between the system and the main water supply. The PVB has a spring-loaded valve that opens when the water pressure in the irrigation system is higher than the main water supply. This allows water to flow into the irrigation system, but if the pressure in the main water supply drops, the spring-loaded valve closes, and the PVB prevents any contaminated water from flowing back into the main water supply.
The PVB is a simple and effective way to protect the main water supply from contamination from irrigation systems. The PVB is relatively easy to install and maintain, and it is required by most water utilities and building codes. The PVB is an important part of any irrigation system, and it can help ensure that the water flowing into homes and businesses is clean and safe to drink. Overall, the PVB is a critical component of a safe and reliable water supply system.
