I am contemplating moving the first floor bathroom in my home.
Unfortunately the place where I would like to move it to is in the
opposite corner of the house from the main soil stack (in fact all the
plumbing in my house is on the rear wall and the new bathroom will be
at the front of the house).
My question is, if I have a plumber put in a whole new sewer
connection (I am assuming this is my only option) in this corner of
the house, does the new main stack vent have to go straight up to the
roof or could it have a 14ft horizontal run before going up to the
I realize that codes vary from place to place but if long horizontal
runs in the main vent is just a general "no way" then I will have to
rethink my whole plan.
