Check Stop Kit for Model TM-15 and TM-20 Thermostatic Mixing Valves

This check stop repair kit is designed to restore proper shutoff and serviceability of compatible thermostatic mixing valves in commercial and institutional plumbing systems. It supports routine maintenance by replacing worn checkstop components, helping extend valve life without the need for full valve replacement. The kit is intended for use with specific thermostatic mixing valve models, including TM-15 and TM-20 series valves. By renewing the checkstop assemblies, maintenance teams can regain isolation capability during servicing while supporting stable system operation.

Constructed as a genuine replacement kit, the components are matched to the original valve design to ensure proper fit and function. This helps reduce downtime during repairs and minimizes the risk of compatibility issues commonly associated with non-OEM alternatives. Common applications include healthcare facilities, schools, multi-family buildings, and commercial restrooms where thermostatic mixing valves require scheduled service to maintain performance and code compliance.
