I'm seriously thinking of adding a half bath to the main floor of my
house. All the necessary plumbing is located in the perfect area.
My only delemma is that I'm not too sure how to attach new PVC to
an old cast iron drain pipe at a right angle. It's very accessable
in the crawl space, about 4 ft of it, but I could use some help as
to the best way to tap into it with a new PVC drain line.
