Thanks. Any info would be helpful and pictures if available.
Very simple, first thing I would check is the outside shower valve is turned off, because it has been known to cause mixing if one of the valves is open. If that's not the culprit the water heater cover will actually just lift out of the closet as it just sits on a small shelf, and you have access to the mixing valve. If you do a search on that mixing valve you will see that it is very easy to fix it by just taking the glue out of the Allen head screw that is on the end of the mixing valveand just turning the knob back-and-forth a few times to loosen up the mineral deposits that seem to keep it from working properly.by turning the knob on the end of the mixing valve you will actually change the temperature of the hot water. The glue was only in there to prevent you from removing the factory set position on that knob. Good luck
