Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Designed for AquaVantage flush valves, Zurn's 3.5 gpf diaphragm repair kit (Part no. P6000-ECA-WS) fits any AquaVantage or diaphragm type water closet valves. With a clog-resistant triple filter diaphragm, its components are made with our chemical-resistant GO BLUE material. GO BLUE parts last up to 10x longer than the competitors', reducing maintenance costs and extending their lifespan. When you need a replacement part for repair or maintenance of a flush valve, trust Zurn for genuine, reliable parts.
