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?
Kitchen sink pipes are usually smaller more delicate than WC pipes. Most people throw food in their sinks, not their WC. All stuff ends in the same place, but the first pipes where stuff goes are different from each other
