Poor hot water quality from insinkerator?
We are putting in a new sink and granite countertop. We received an insinkerator hot water dispenser about 4 years ago as a present and are considering installing it at this time (in addition to an RO system). I have read here that you can't really run the pure water thru the insinkerator, because the water is hard on the metal parts. That issue aside, I always thought that the hot water was kinda scaley because it sat around in a reservoir. Is this true?
