Why are you allowed to insert the drain hose from a clothes washing machine into the standpipe or into the laundry sink, but for other things you are supposed to have the discharge above the rim of the standpipe or sink? As far as I can tell, you are not supposed to even let the drain hose from a softener be right down to the floor-level grate. That one, as has been discussed, is a bit paranoid by the rule makers.
A humidifier overflow and a bunch of things are suppose to have an air gap I think.
How did the washing machine escape so far? Maybe because the rule makers all have washing machines?
I am not arguing for washing machine drain connections to have air gaps.
Any speculation on this?
