Old Toilet Flange on cast iron pipe
2 Attachment(s)
This toilet has probably been sitting here for the greater half of a century. It began leaking onto the floor so I decided it would be a good idea to replace the wax ring. First, this toilet had four bolts. Two of which were mounted into the bare tile and two into what I believe is the flange. When removing I discovered that only one was not complete rusted out. After scrubbing for about 3 hours here is the result. They must have used some clay type of wax ring. I can't tell where the wax ring starts and the flange begins. It is all very dense material a little more than my flimsy putty knife can handle. I don't think it will be possible to salvage the existing flange. I was thinking of getting a "super flange" or some sort of compression flange. Any suggestions?

What type of access to the plumbing do you have?

It is partially embedded in the plaster ceiling of my garage. it doesn't go very far before it meets the sink and main drain lines.

So I had a plumber look at it. I did not even have a flange! This is common in houses built in the 50s and earlier.

My neighbor lent me a tool to grind down the excess pipe. I bent the bolt until it broke at the floor and used the tool to grind everything pretty smooth to the surface of the tiles.

I used a putty knife to get the crud off the inside of the pipe.

Then I installed a twist and set flange. You place it inside the pipe, twisting it will raise a rubber seal until it is tight inside your pipe. I then mounted it to the floor with screws.

I installed a new toilet and everything is working great!
