Do you get hot water out of the other taps? My shower mixing valve seems to plug up and I believe its either rust or sediment in the valve. Cold pressure is strong. Replacing the mixing valve in the shower involves taking the washer and dryer out of the adjacent space. Not too easy of a job? Shower works better if connected to city water with higher pressure. Other than that it would seem that the hot supply going into or out of the Aqua Hot is plugged?
