Thermostatic Mixing Valve Troubleshooting
Prior to February 1, 2013
Before attempting to troubleshoot the valve or disassemble the components, check for the following conditions:
• If stop valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no cross-connections
or leaking stop valves.
• Check the hot water heater output to make sure that it is at least 10° F above the set temperature.
Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen the valves after
inspection and repair is complete.
