We had another Insinkerator hot water dispenser with a button to push instead of a lever. We had it exactly 2 years and it started leaking and would not stop. We called the help line and they tried to help us but the leaking would not stop. Unfortunately we were out of warranty so we had to buy a new one. This new one has been installed about a month and we love it. We find we prefer the lever and so far it works perfectly.
