Originally we were going to hire a plumber to install the insinkerator. After looking over the easy-to-read and easy-to-understand instructions, my husband decided to give it a try. Within a half hour, he had the old insinkerator out and was finishing up with the installation of the new one. EasyPeezee. :) I use the insinkerator every morning to make my oatmeal without having to cook or microwave, have a cup of coffee or tea, sterilize eating utensils when someone has a cold.... the uses are endless. I can't imagine having a kitchen without this appliance. Do yourself a favor, and treat yourself to this inexpensive yet priceless item. You won't regret it.
