Some people call them waste disposers, some people call the garbage disposals.  Same difference.  Whatever, when you're buying one, you'd like to be an educated consumer.  This site is dedicated to helping you understand what you're buying a little better.

To start with, I provide a brief description of how a disposer works.

There are several features that separate one model from another, including power, materials, noise, and an assortment of other features.  I also make a few comments about companies and models available and the warranties offered.

There's also some instructions on how to plumb your disposer.
