Hi, I'm remodeling my master bathroom and I'm looking for advice on what to do with the toilet flange. The house is ~50 years old and the existing flange isn't cracked or broken, but it does look badly corroded on the inside of the flange and pipe. I was originally planning to leave it as it is, but I'm concerned about it leaking in the future. I don't really have a way of measuring how much wall thickness is left. I'm thinking that my options are:
- Leave the existing flange there and hope for the best. I'm not that comfortable with this option because I would hate to have it leak and drip down on the first floor.
- Cut the 3" cast iron pipe on the horizontal run a few inches before the hub at the stack. Then I would put in a new ABS flange and pipe and connect to the existing cast iron pipe using a Fernco type rubber coupling.
- Cut/chisel the old cast iron pipe out of the hub at the stack. Then put in new pipe to the hub. I'm not familiar with what the best practice is for sealing a new pipe into an old cast hub like that.
