Troubleshooting

Fluctuating or erratic hot water temperature at fixture:
Unbalanced pressure. Install balancing or throttling valve at the
hot and cold water supplies and adjust accordingly for demand.
Hot water backing up into cold water line:
Hot water pressure is higher than cold water pressure.
Examine check valves for dirt & debris, clean as necessary.
Cannot adjust water temperature to desired temperature:
Install balancing or throttling valve at the hot and cold water sup-
plies and adjust accordingly for demand.
High pressure drop through the tempering valve:
Valve undersized. Install larger thermostatic tempering valve.
Insufficient hot water during peak demand:
Check flow requirement during peak demand period. Use larger
thermostatic tempering valve.
