Second opinion on plumbing plan

[itsjustfarris]

doing a new install and haven’t used AAVs much before, wanted to get a second opinion on the layout and if I was missing anything. Also the kitchen sink drain will be exposed coming up in the middle of the cabinet and. I wanted to know if anyone has any good tips or tricks on how to better do that. Thanks all and I hope my middle school art class was enough for this picture haha

Only bathroom fixtures can be on a wet vent. The kitchen sink can't be included with that. The kitchen sink should come in downstream of the bathroom.

So the drain on the sink needs to run down (kind of parallel) and tie in past the toilet? Anything else?

You need proper sized cleanouts. 3" on the toilet and 2" on the kitchen sink.

And that’s it, all else is good? Thank you for helping!

I have never HAD to connect the kitchen sinks after the bathroom. In fact, I have NEVER done it unless that is how the house was arranged, (and it is not how MY plumbing is done in my own house).

So it would be fine to still tie it in like it’s pictured?

As far as I can tell Terry seems totally correct . Kitchen drain must not be flowing through the wet vent for a bathroom group. Me , Terry, and HJ are professionals but others may chime in. HJ might not have noticed that there was a horizontal wet vent I cant say why he has different opinion.
I would recommend ditching the AAV unless there is a problem tying a vent to the stack just makes it a little cleaner and vents wont fail
