Description
The Watts HY-400-PVB Vacuum Breaker is used to prevent reverse water flow and protect supply line from potential contamination caused by back siphonage conditions. Operating with a pressure vacuum breaker mechanism, the system allows air entry when required to interrupt unwanted reverse flow and maintain proper water direction. Frequently used in boiler connections, water supply lines, and plumbing protection applications associated with HVAC systems, it helps maintain safe fluid control during operation. Attached to compatible piping arrangements during servicing or replacement procedures, the vacuum breaker helps preserve proper flow separation and reduce the water supply contamination.
