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?

    Food itself isn’t the issue - it’s the big chunks and oil/grease/fat. It’s better to pour it down the toilet, since the volume of water you flush it with is greater and the drain diameter there is larger as well (110 mm) compared to the pipes under your sink, which are usually 75 mm in diameter, sometimes even just 50 mm. Solids are also more likely to clog the P-trap under your kitchen sink.

    Eventually, it all ends up in the same drain system anyway, so in that sense there’s no real difference.
