Maintenance Tips

• Inspect the valve annually and verify downstream pressure to ensure accurate pressure regulation and reliable operation.
• Check regularly for leaks, pressure fluctuations, or pressure creep, and clean the internal cartridge and strainer if sediment or debris is present.
• Flush the water line before servicing and keep the integral strainer clean to maintain consistent flow and performance.
• Adjust the pressure only with a downstream pressure gauge, following the manufacturer's recommended pressure range.
• Replace worn cartridges, seals, and internal components using genuine Zurn Wilkins repair kits to maintain long-term reliability.
• After maintenance, confirm the pressure setting and inspect all connections for leaks before returning the valve to service.
