My house dates to the 1890's. When the toilet was removed we found a lead closet bend attached to a cast iron pipe. Nothing is cracked. The Floor Flange is cast iron as well. I have had two plumbers in to give me opinions. They say the lead pipe has to come out. The cast iron pipe is in the wall and very difficult to cut in that position so they recommend that I have the wall below the toilet in my pantry opened up so that they can cut the cast iron pipe there and replace it with PVC pipe. They will also cut the same cast iron pipe where it extends into the basement so they can start the PVC pipe there. I understand from my carpenter that cast iron pipe is very heavy and they may need to go up to the third floor as well. As this seems extreme I am looking for alternative suggestions.
