This my second Insinkerator hot water dispenser. The first one developed a leak after five years of use. That model was discontinued and the Insinkerator rep recommend this replacement model with a filter system as well. While not a plumber, I consider myself a capable handy man around the house and was able to install the new model fairly easily. The one complaint I have is the length of the hoses and copper tubes provided with the unit and the faucet. The space under the sink was cramped due to dishwasher hoses, water & drain pipes and a large Insinkerator disposal making it difficult to place the unit and filter where I wanted it. I ended up having to put the filter way in the back of the cabinet, where it will be difficult to change out when the time comes.
