I never knew how much I depended on my hot water dispenser until mine died....in fact, I never had one until we purchased this house and one was installed. My husband gave me my Insinkeraror replacement as my Christmas gift and arranged the installation for the absolute perfect gift for me. He heard me complain about not having a working one and knew nothing would be appreciated as much. The only change I would make in the design would be to have a lever instead of the turn knob. Those of us with hand arthritis would find it easier to turn with a lever.
