I am remodeling a bathroom and I want to move the sink to another wall; opposite the toilet wall. I am wondering about how to vent the drain. Is there a way I can put in an in-line vent that vents in the wall?...or can I vent it out an exterior wall? I am on the second floor of a three flat so I don't have access to the roof for draining. what is the easiest way to do this????
thanks
