See picture.
Red is current plan, green is proposed.
The 1st floor WC drains into the 3" pipe with a (to be added) 3" to 2" dry vent to roof as indicated.
If I wanted to tie in a 2nd toilet from the floor above, would I have to add a dry vent for the lower WC in the location shown ?
I assume that I can't wet vent the first floor WC through the same 3" pipe that the 2nd floor WC drains into.
thanks.
