Adding a dishwasher drain to an auxiliary/revent

[kronos288]

Need some assistance on this one! I haven't been able plumber locally that can do the work within a reasonable timeframe (multiweek wait).

I've more or less determined that the connection shown by the question mark from "Marked 3" is an auxiliary/revent from the basement bathroom sink and/or shower.

Question: Can I add a wye and tie in the dishwasher discharge plumbing from the kitchen cabinet (an AAV with a trap) to the horizontal auxiliary/revent shown in the photo "Marked 3"? If not, my options become limited as I'm having trouble finding a proper fitting for 1 1/4" copper DWV to tie directly into the vertical stack shown in the photo.

FYI - the dishwasher is located in a peninsula too far from the kitchen sink.

Thanks for any help in advance .

No. Dishwashers must be piped indirectly via an air gap into a nearby sink, or if you want to dirtbag it, then via a high loop.
You can pipe the DW hose under the floor then up into the sink cabinet to the air gap.

Thanks for replying! Code here allows an AAV during a remodel. My original plan was to use the AAV, high loop the dishwasher hose as per the manufacturer's guide, then run the ABS drain from the cabinet beside the dishwasher into a wye on the auxiliary/revent.

The better way would be to extend the dishwasher drain hose under the floor, across the kitchen, and back up into the sink cabinet?

I don’t agree with running the hose down and then across the floor and back into the cabinet. This puts a lot of head pressure on the pump. I’ve read it’s not recommend.

But that’s my opinion and what I’ve read

What good would an air gap be with 15’ of hose between the dishwasher and said air gap ?

That hose would stay full of death water from the dishwasher to said airgap.
