Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Zurn’s piston replacement kit (Part no. PTR6200-EU) is designed for EcoVantage® ZTR 0.5 and 1.0 gpf sensor urinals. EcoVantage® ZTR flush valves feature a piston-type design with clog-resistant components and a chemical-resistant GO BLUE® internal seal for an extended lifespan and lower maintenance costs. When you need a replacement part for repair or maintenance of a flush valve, trust Zurn for genuine, reliable parts.
