The disposal tends to allow guck to siphon back into it. UGH.
Current plumbing code requires a separate drain for the DW, or so my plumber told me. Any changes to the plumbing require a retrofit. I'm really glad that when we remodeled the kitchen a couple of years back that we redid all the plumbing. Apparently, you can replace the DW without upgrading, but it's getting harder to find a disposal with the DW fitting these days.
