Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Designed for AquaFlush flush valves, Zurn’s 3.5 gpf diaphragm repair kit (Part no. P6000-ECR-WS) fits any AquaFlush or diaphragm type water closet valves. With a dual-seal diaphragm with a clog-resistant bypass and chloramine-resistant seals, 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.
