On to the next bathroom that needs to be completed. This should be pretty straightforward. Is this layout acceptable (see attached pic)? A few questions:
1) Is the single 2" vertical stack vent appropriate for the water closet and the shower?
2) Is the best choice a 3" double wye (with reducer for the 2 "shower trap arm of course) for the water closet and shower and then a 2" santee above that for the lav drain?
3) I assume that since the double lav is over 8' away from the stack, I will need to re-vent those, correct?
Note, I intend to vent the bar sink that is on the first story up to the vent. As always I really appreciate the help on this forum!
