You should have a licensed electrician do the wiring beforehand: you’ll need a ground fault circuit interrupter outlet under the sink to plug the unit in and a separate switch placed far enough away to meet your building code.

A mounting assembly seals to the sink drain flange with plumber’s putty, with rings and screws to support the disposal as it hangs below the sink. There’s a knockout for connecting your dishwasher’s drain tube and a connector for the waste line.

If you’re shopping for a new disposer, you can spend between eighty and four hundred dollars for a unit warranteed for between one and ten years. Look for a model with a half- horsepower or more for the best durability and clog protection.

Generally speaking, the larger the unit’s body and the finer the grinder, the quieter it will be.
