Watts RK-009-CK1 Check Valve Repair Kit

Watts RK-009-CK1 Check Valve Repair Kit is a genuine OEM first-check repair kit engineered for Watts 009 and LF009 RPZ backflow preventers. Designed for 1-1/4" to 2" assemblies, it provides the components necessary to restore proper operation of the first check valve, helping prevent reverse flow and extend the service life of the RPZ unit. Replacing worn first-check components helps restore valve performance, prevent reverse flow, and maintain compliance with plumbing and cross-connection control requirements. Applications span commercial buildings, municipal water systems, industrial facilities, hospitals, schools, irrigation systems, and fire-protection installations. Intended for preventive maintenance and internal repair of existing backflow preventers, this kit supports potable water systems across commercial, industrial, municipal, irrigation, and fire protection applications, and is commonly used by plumbers, maintenance technicians, and facility managers to maintain cross-connection control compliance. The RK-009-CK1 is compatible with Watts 009 and LF009 RPZ models and is an OEM replacement part that enables internal service of the first check valve in potable water systems.
