Wilkins rk1-375v Valve Repair Kit Relief Valve

Product Description

The WILKINS rk1-375v is a valve repair kit designed to maintain and restore relief valves used in commercial and residential plumbing systems. The kit supplies the consumable internal components that wear over time, allowing a licensed plumber or certified backflow technician to return a valve to proper working condition without full replacement. It includes O-rings, test cocks, and a working pressure vessel — the three components most commonly degraded through normal service cycles. Materials are rubber and steel, suitable for operating temperatures between 33 degrees F and 140 degrees F.

This repair kit is intended for use during scheduled maintenance, annual backflow preventer testing, or corrective service on relief valve assemblies. It is well suited for commercial mechanical rooms, irrigation systems, and potable water plumbing where relief valves must meet local inspection and testing requirements. Technicians working under ASSE, AWWA, or local cross-connection control programs will find this kit appropriate for in-field restoration work on compatible valve assemblies.

Installation Notes

Installation should be performed by a licensed plumber or certified backflow assembly tester in accordance with local plumbing codes and cross-connection control program requirements. Shut off the water supply and relieve system pressure completely before disassembling the valve. Do not reinstall the valve assembly without verifying that all components are seated correctly and testing the assembly per local authority requirements after service.
