      Christopher AllenJul 27, 2025
      If the mixing valves on your Hyco Water Heater aren't working, it could be due to unbalanced pressure. Make sure the cold water is correctly tee-ed off after the pressure reducing valve, so both hot and cold water are at equal pressure.

      If your Hyco Water Heater isn't heating water, it could be due to several reasons. The thermal cut-out may need resetting. Alternatively, there might be an element, thermostat, or thermal cut-out failure, requiring replacement. Also, check that there is an electrical supply.

      Fred FosterAug 6, 2025
      If water is constantly discharged from your Hyco Water Heater, it could be because the pressure reducing valve isn't properly reducing water pressure, or a safety valve is operating below its nominal level. You may need to replace the appropriate valve.
