Hi, Guys. Bath remodel is coming along nicely, due in large part to the great advice I've received here. I've hit another wall, so hoping someone can again point to the best solution.
I've removed the old vinyl flooring and 3/8" underlayment, and am currently repairing the subfloor (1x6 planking) in preparation for new 1/2" ply underlayment, Ditra, and tile. I'm estimating the new floor will be raised by ~1/2" when done, which will mean addressing the current toilet flange. It is in decent structural shape as far as I can tell, but there is considerable corrosion on the elbow it's attached to. The flange doesn't appear to be the leaded-in type I've read about in my research, but rather a two piece compression deal. Ideally (I'm guessing), I'd just remove the current flange and replace with a new PVC one. Unfortunately the flange and elbow are now essentially one solid piece, so there's little hope of removing it without compromising the elbow.
So, simply put, how best can I raise the flange to the new finished floor height?
The options I'm considering so far:
- Install the underlayment around the current flange, and add an appropriate spacer and new flange once the new floor is installed. Clearly the easiest route, but not sure I'd ever feel completely comfortable knowing the condition of the old plumbing I'd built on top of.
-Find a suitable place to cut the iron (see pic), and replace with a fernco coupler and ABS. This is a much more difficult, but possible, proposition, due both to access issues and a substantial expansion of the scope of the project.
-Move ;-)
Have I missed something obvious? Certainly wouldn't be the first time.
I've attached a few pics to better illustrate the situation. Thanks as always for any advice you might provide.
Current flange and elbow:
Elbow to wye junction. Down continues to drain, up is the vent:
Coupling below the wye. This seems the best place to switch to ABS:
Below the coupling, continuing to main drain:
Galvanized vent line w/ massive coupling to work around:
