The LEONARD VALVE KIT 1/M10 is a thermostat replacement kit designed for use with the Leonard M10 mixing valve. This kit provides the internal thermostat components needed to restore accurate temperature regulation in thermostatic mixing valve assemblies. It is the appropriate service part when the existing thermostat element has failed or is no longer maintaining proper mixed-water outlet temperatures. Licensed plumbers and commercial facilities maintenance technicians are the typical installers for this type of repair kit.
This thermostat kit is suited for repair and maintenance of thermostatic mixing valve installations in commercial and institutional plumbing systems, including hospitals, schools, and lodging facilities where scald protection and consistent hot water delivery are required. It is intended for use specifically with the Leonard M10 valve body and should not be substituted into other valve series without confirming compatibility.
Designed as an OEM-style replacement thermostat kit for the Leonard M10 thermostatic mixing valve.
Installation should be performed by a licensed plumber familiar with thermostatic mixing valve service procedures. Shut off the hot and cold water supplies and relieve system pressure before disassembling the valve. Follow the valve manufacturer's service documentation for proper component seating and reassembly sequence. Verify outlet temperature with a calibrated thermometer after reassembly to confirm correct operation.
