I'm wondering if it would be possible to make the washer's cold water tap warm. Is there a code issue with that? Could a wye be installed that joined both hot and cold before the valve. Is there a mixing valve to warm water that could replace a washer valve?
Reason for asking:
I am researching the new washers and I am finding that the manufacturers are making it so you can't get a true hot wash unless you have an onboard heater which adds about 90 minutes to the wash time. Even then, the manufacturers decide what they consider an acceptable temperature to be. One targets hot at 110 with the onboard heater. They won't tell you unless questioned, but that same manufacturer stated their target range for hot as 90 to 100 degrees. without heater and they allow little hot input on warm cycle selections. Guess they figure the ambient temperature will warm the water. They assume that the water will be 64 degrees. We have a well, and it's not nearly that warm.
I am chemically sensitive and my research suggests that to avoid using chemicals to clean the bio-film off the washer which feeds mold and mildew, one needs to use very hot water at least once every 5 loads as well as drying the gasket thoroughly after use and leaving the door ajar so the washer dries out after the last load.
