Prevent backflow and back-siphonage into potable water with a Zurn vacuum breaker. Constructed with our chemical-resistant GO BLUE® material, the vacuum breaker is built to last. GO BLUE® parts last up to 10x longer than the competitors’, reducing maintenance costs and extending their lifespan. The kit (part no. P6003-A-CP) includes a vacuum breaker and a ¾ x 8 ½-inch flush tube. The flush tube is constructed of a durable, dezincification-resistant chrome-plated cast brass. The set works with ZEMS 6000 series of flush valves to keep drinking water from becoming contaminated. When a vacuum breaker is needed for repair or maintenance, trust Zurn for genuine, reliable parts.
