Every dishwasher installation manual I have seen talks about a high loop and/or air gap in the drain hose. I understand that. Every dishwasher installation manual also prohibits running the drain pipe up the back of the dishwasher. They insist that the drain hose go through the cabinet at the lowest point, then up to the high loop or air gap. For example, see attached from GE.
In my new house, they ran the drain hose through a hole in the top of the cabinet, just under the countertop, then down to the disposal, serving as a high loop. See attached photo. That clearly violates the instructions.
When I complained, they said that they always do it that way. After a little research, it seems that lots of people do it that way.
Why do the manuals prohibit running the hose up the back of the dishwasher and across just under the countertop? Is this important or just a minor detail?
Thank you.
