I have used the insinkerator hot water dispensers in 4 different simultaneous installations for years. I just bought this new heater tank to replace an out of warranty broken tank. The water has a terrible odor and taste, the help line will only give me a repair phone number and tell me if it is not a manufacturing defect I have to pay the full cost of the visit. I can't afford to take this chance when I have never had this problem before. Just send me another tank!!!
