Champion 0502751 Vacuum Breaker 6-7/8" Handle 1-1/4" FPT

The Champion 0502751 Vacuum Breaker 6-7/8" Handle 1-1/4" FPT is a vacuum breaker that interrupts reverse water flow by admitting air when negative pressure occurs in a commercial systems. It operates through a spring-loaded internal check mechanism that seals the water passage under normal flow and opens instantly under vacuum conditions, allowing atmospheric air to enter the line and equalize pressure within the system. It is installed in plumbing or water supply lines, typically at hose connections or equipment inlets, positioned to prevent contamination risk from backflow situations in pressurized systems within commercial plumbing installations and water distribution networks as a required unit.
