Please take a look at the attached model I just quickly drew. Whoever did the work previously made swiss cheese out of a 2x4 load bearing wall that I'm replacing with a new 2x6 wall to accomodate the proper piping thats replacing pretty much everything but the main stack. You dont even want to see what was there before. So light me up, whats wrong with what I have here? What can I clarify better? And I follow UPC.
Can i wet vent the shower like that?
