I am in the last leg of a kitchen remodel and need to purchase a garbage disposal. And I am wondering how much of a difference horse power makes in the day to day operation of the kitchen?

Has anyone here experienced the pros and cons to disposal units with different horse power?

NOTE: I almost posted this question on the DIY site, but I feel it has more relevance here. Moderators, feel free to move it if you think it belongs there instead.

UPDATE: We decided to go with the Waste King L-8000 Legend Series 1 Horsepower. It is really smooth and quiet. It takes up a fair amount of space under the sink however.

  • The answer depends... are you trying to put food down them, or your neighbor's yapping chihuahua?

I'd go for a more powerful one, in general, and I noticed that the higher powered disposals are sometimes quieter, which I really like. I really learned that paying the extra for good plumbing parts (faucet, disposal) through our plumber was worth it, since they can be fixed, unlike cheaper big box store stuff, and that there was a real difference in the higher quality disposal.


My impression is that horsepower is really only going to matter when you've got something stuck in the teeth. Once or twice I've had this happen, where something has gotten stuck in there (say, a piece of broken glass, or an unpopped popcorn kernel). The machine grinders give up and the whole works just stop moving and I've had to turn it manually (using a wrench on the underside of the disposal) until it was crushed. More horsepower just means it will give up a little less easily.


Ray has raised very important point here, it depends on the materials it grinds, if hard materials it has to grind, horsepower is very important here.

  • Hello grmary, and welcome to the site. While we generally allow links to commercial products which answer a question directly, they should not be used if the answer is as informative without them as it would have been with them. Also, users may react negatively to them even when they don't hurt the rules. I don't have to delete the post after I removed the link, but for future reference, it's better to leave it out from the beginning.
