All,
I've been lurking on Terry Love's forums for several weeks now and have really appreciated the discussions to-date. This is my first post, so please excuse me in advance if I sound a little naive or am asking something that has been answered elsewhere.
I'm working on a remodel of my ground floor bath and am struggling with something a little beyond my experience. The remodel is a total strip -- 80yo house, 3.5" of mortar and tile, ancient cast iron tub, galvanized water lines, knob-and-tube, you get the picture -- and as you can see, I'm down to joists and studs at this point.
My problem is with the location of the current toilet drain in the original cast iron stack. I've removed the original closet and lead pipe and chiselled everything out of the hub, but the fact remains that the top of the hub is flush with the top of the joist/underside of the subfloor. Even though the run is nominal, I don't believe there is enough room to turn the pipe leading from the closet, let alone maintain any kind of slope.
Because the "T" is cut into the joist and leads to a "Y" almost immediately below it, I also can't figure out a reasonable way replace it without doing a wholesale re-plumb (time to call in a pro at that point).
What I'm proposing to do is to cut into the waste pipe in the crawl space below -- ideally at the red arrow, possibly at the green arrow. The latter requires more angle fitting than I like, but I don't know if I can cut into the section indicated by the red arrow and still meet code (it's a relatively short run, ~18" from hub to hub).
I would welcome any comments or suggestion on any of the above. Should I go ahead and try to make the pipe fit to the existing "T"? Can I plug the "T" and cut into either of the two locations in the crawlspace? Or is it time to call in the cavalry and re-work the entire vent stack and waste connection?
Thanks in advance...
Jay
