I went to replace a toilet and it has an offset toilet flange and the slots are on three sides the other side had a plastic extension for the bolt with is broken. I believe it is all pvc. I went to a plumbing store and he said you can't just put a ring on top of it. I looked on line and that is pretty much what I read also. The plumber at the store was saying you have to cut it out and replace it with an extension and new offset flange.
I'm trying to get all the options before I decide which way I'll go. If I do need to cut it out it looks like it could be difficult for someone who has never done one of these before.I've read it needs to be done with a certain tool that cuts the pipe from the inside.
I've got a couple bath rooms so I could take my time with it but don't want to take on something that is not going to be the best option. Any insight from an experienced person with offset flanges and what difficulties can be expected when one is a novice? A plumber seems like the best option to me but am willing to check things out before I go that way. I looked at other web sites and someone had a similar situation and one of the responses was in pictures on which flange not to put in and that was the one I have.
