Bleah. I still don't have a working garbage disposer. I bought a new disposer. Even though I bought the same make and model, the drain for the new disposer is a different attachment type than the old.

Now I'm going back. I'm going to buy the wrench that unjams disposers. (Thanks to whoever mentioned it) I'm also going to buy the right tubing to hook the new disposer up. We'll see what's easiest.
