In my upcoming kitchen cabinet replacement, I'm getting a single dishwasher drawer to replace a full sized one and I want to install it at height of about 35" (that's its bottom, so the top will be at about 51" from the floor). It will most likely be hooked up to drain into the garbage disposal which is under the sink right next to it.
All installation instructions and all related questions I could find talk about draining assuming that the dishwasher is next to the sink, which this one is next to the sink, it will be higher than the sink.
What changes would need to be made to the draining set-up for the dishwasher drawer in this scenario? Given that the bottom of the drawer will be roughly at the same height as the very top edge of the sink, it seems unlikely that any blockage would cause backflow would end up in the dishwasher, so does this mean there's no point to air gaps or looping the drain hose under the counter?
