I’ve heard multiple times that it’s not okay to allow any food to go down the drain even with a garbage disposal, I guess because solids shouldn’t go down the drain. But we put a shit ton of solids down the drain through the toilet and that seems to be fine. Does the toilet go to a different sewage pipe then the sink? Or does shit have different properties that make it dissolve better?
I’d also point out that the toilet pipe is significantly larger than than the kitchen pipe, and uses a multi-gallon, siphon-powered flush to help move it along. Your kitchen sink has none of these plumbing advantages. If you wanted to have a 3 inch kitchen drain and some kind of powered flush apparatus you might have a better time with food waste, but it’s still probably not a good idea for the reasons other people have mentioned. A normal kitchen sink drain configuration, even with the assistance of a disposal, is still quite ill-equipped to handle that kind and quantity of waste.
So don’t poop in the kitchen sink. Got it!
It’s ok to shit in someone else’s, just not yours.
3 inch pipe? I saw that movie… well parts
