Toilet Flange
Good Morning.
I have a situation that I am not sure how to handle. Hopefully, someone can guide me in the right direction. I have a house that I bought 2 years ago and some "re-modeling" was done by the previous owners and might I add it was done poorly! Anyway, we went to replace the toilet and we found that they had tiled the floor and then just sat the toilet on the floor. It wasn't even bolted down. After further investigation we now know why. The flange is completely rusted to the pipe (original, I'm guessing) The house was built in 1957. They used grout and pushed another one on top of it. So now all of that is sandwiched together and the bolts are stripped. I want to replace the tile (the goal here) but, in order to do so I would need to fix the toilet issue. The flange's are rusted onto the pipe which is now below grade due to the tile. I was told that the only way to get this fixed is to have that part of the foundation jack hammered out and a pipe extension put on with a new flange and fill in the foundation with new concrete. This sounds like a lot of work, money and trouble for a new flange just so I can have new tile. Any suggestions or comments would be greatly appreciated.

When I put a new floor in my bathroom, and found a broken cast iron flange (1900-ish plumbing stack), I got a PVC replacement flange that had a rubber collar around the outside of a short pipe. The pipe went inside the cast iron drain, and then by tightening a few bolts, the rubber collar expanded to hold the new flange in place. It created a very solid fit, and was quite easy.

I am not sure if I understand the meaning of "foundation jack hammered out", if it means to get some concrete out of the floor to do the fixing... then I think this step you cannot avoid... it is rather common to fix toilet drain like that.... you can do this yourself to save money... it take time to break some concrete, just need to be patient... I used to require to break a little bit of concrete to put in a flange on the outside diameter of the drain pipe... I did it with some effort an patient... same requires here...

I don't think you need to break the concrete. Simply use a double-thickness wax ring, or use a replacement flange like I described.

may be you are right with the special flange .... just make sure there is no compromise in the size of the hole.... as I used to able to use some special flange which also fit inside but it compromise the size of the hole and after study more it is kind of against the code....

Toilet Flange
Thanks for the advice. I will go and see what I can find at HD or Lowes with regard to what you were talking about, NateHanson. It just sounded like a major overhaul based on what I was told. Just out of concern, what if the pipe that the flange is rusted or is damaged? Will that require going into the concrete slab (foundation) to fix the pipe? This is what I was referring to as far as jack hammering the foundation.
