The list could go on and on but why bother as clients could care less about these things ...right

I mean door pads not on cabinets are just noisy and door stops are only needed if you do not put a cast iron dog behind them and do horizontal closet door really need guides ?as all they do is stop them from flapping So.

Some people are just too picky,but I am one of them.

Seriously Mark the potential is there for contamination if it does back up onto the dishes and you are unaware.
You may have got sick one day and it was from some rotted cr-p that you never knew about.

Do not mean to yank your chain but I had a long drive today.

Does there need to be a high loop (in my area is is permitted) when the DW doesn't connect directly to the disposal? See the attached pic. DW has no high loop, connects to the tail piece on the left sink.

I do not believe so Joe, but I am not positive.

Joe I used to install these every day for Sears and I can tell you that some have it built in ,but since you do not know which,it is an easy fix to have them tie it up high under the counter.

Bob, thanks. But is it REQUIRED?

Depends on AHJ near you.
In Chicago the airgap devices are required but high loops accepted.
Hell with code as I would recommend it.

After looking at it again Joe, I would say yes. If the trap is cloged, the drain will back up until it reaches the DW drain line and then run back into the DW. The reason the high loop goes up to the bottom the flood rim is so when there is a backup you will see the water in the sink.

I totally disagree.

I tell all my clients how to fix/repair most simple defects, and explaining a high loop installation takes me approximately 15 seconds.

In Illinois, yes.

a) Domestic Dishwasher (Private Residence). When a domestic dishwashing machine drain line is connected to the house side of a trap from a sink, the drain from the dishwasher shall be carried up to the underside of the spill rim of the sink. Dishwashing machines shall discharge separately into a trap or tail piece of the kitchen sink and shall not connect to the food waste disposal unit.

If your AHJ goes by IRC, then yes. Loop should extend to underside of counter. Sinks without disposers can back up too
