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. P6000-3-A-AA-CP) includes a vacuum breaker, 1 ½ X 24-inch flush tube, and nut. The flush tube is constructed of a durable, dezincification-resistant chrome-plated cast brass. The set works with AquaVantage and AquaFlush 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. Material: Plastic.
