Troubleshooting Thermostatic Mixing Valves

Before troubleshooting the valve or disassembling the components, check for the following conditions.
• Be sure to properly connect the hot and cold inlet pipes. Verify there are no cross-connections or
leaking valves.
• Verify the hot water inlet temperature is at least 120°F.
• Be sure to close the appropriate shut-off valves prior to disassembling the valve. Reopen the valves
after inspection and any repairs are complete.
