My dishwasher drains to a basement washtub, unfortunately dishwasher
couldnt go by sink its across the room. trust me the loop is necessary
or the water will siphon from the machine

Interesting, not a single manual for a DW I've read mentions draining
to a basement. Seems every one does mention using the hose in a loop
- with or without an air gap... an always mention the sink, adjacent.

I vote for the loop
