Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Designed for AquaFlush flush valves, Zurn’s diaphragm (Part no. P6000-ER15) can be used with AquaFlush, AquaVantage, or diaphragm-type flush valves. The diaphragm is made with our chemical-resistant GO BLUE® material. GO BLUE parts are designed to reduce maintenance costs and extend the lifespan of the product. When you need a replacement part for repair or maintenance of a flush valve, trust Zurn for genuine, reliable parts.
