This hot water dispenser replaced an older InSinkErator model that we had for 10 years. Our old unit had developed a leak but other than that was working just fine. The water temperature adjustment on this new unit is much easier to use and the handle is easier to turn but it does make more noise while it is heating water. Installation went pretty well but there was one necessary fitting that didn't come in the box. Our plumber was able to supply the fitting from his stock on his truck. If we had been doing the installation, we would have had a 40 minute round trip to the plumbing store in town to get the fitting.
