SERVICING AND INSPECTION
• Inspect the TMV at least once per year to verify it is operating correctly. It may be necessary to check the valve more
frequently in installations with poor or unknown water quality. Outlet temperature may vary due to seasonal changes in cold
water supply temperatures.
• When testing, verify the temperature at the same water outlet measured during initial setup. Allow water temperature to
stabilize before measuring. If the temperature differs more than 5°F from initial setup, refer to the troubleshooting table below.
Problem
Unable or difficult to set correct
mixed water temperature
Mixed water temperature is not
stable or changes over time
Full hot or full cold water flowing from MIX outlet
No flow from MIX outlet
Reduced or inconsistent flow rate
Mixed water temperature remains
same when handle is moved
Hot water flows into the cold water system,
or cold water flows into hot water system
TMV is noisy

1. As tested in accordance with ASSE1017.
2. This is the minimum difference required between the valve outlet temperature and the hot supply temperature to enable
the valve to function correctly and ensure shut-off of outlet flow in the event of cold supply failure.
3. Maximum permitted variation in either supply pressure in order to control the outlet temperature to within ±5°F.
Excessive changes in supply pressures may cause changes in outlet temperature.

Solution
• Ensure inlet temperatures meet TMV specifications
• Ensure that hot and cold supply lines have not been reversed
• Ensure strainers are not blocked
• Ensure strainers are not blocked
• Ensure supply pressures are stable. Install
pressure regulating valves to correct
• Verify valve temperature setting
• Ensure that hot and cold supply lines have not been reversed
• Ensure that check valves are not clogged or damaged
• Ensure inlet temperatures meet TMV specifications
• Ensure adequate hot or cold water supply
• Ensure inlets are not blocked
• Ensure inlets are not blocked
• Ensure supply pressures are stable. Install
pressure regulating valves to correct
• Ensure that hot and cold supply lines have not been reversed
• Ensure that check valves are not clogged or damaged
• Ensure water supply pressures are within TMV specifications.
