I am a new homeowner with very little knowledge of plumbing. We decided to replace the old toilet upstairs for a new and more efficient one. The old one would also leak occasionally when flushed, near where the bowl meets the tank.

Once we removed the old toilet we saw the flange was old and rusted and has a crack on one side. The flange is some type of metal and goes around the outside of a 4" pipe that is metal as well. I purchased a new Sioux Chief 4" PVC flange that will go inside the pipe. I am not sure if it is recommended to remove the old flange prior to installing the one. I am having difficulty getting it over the lip of the pipe. The lip of the pipe seems bend a little so I am not sure if that is actually the pipe itself, although it runs right to the pipe. There appears to be a small crack on the lip of the pipe as well. Is it recommended to stick with the old flange and get a cover to go over the crack or just replace. Would the inside pvc flange work better, even with a 4" metal pipe?
I would think this would leave a gap in the floor when previously filled by the outside flange.
I do not see an option to post pictures
Thanks any for any help.

The PVC flange will NOT attach to a metal pipe, and we would need a picture of what your flange looks like to decide on a repair method.

I purchased a 4 inch PVC DWV Gasket Closer Flange.


It is sounding like I shouldn't bother with the new flange and use a repair ring. Is it better to keep the metal pipe and metal flange?

I am concerned with the curvature of the pipe at the top. Is it normal to not be level with the floor and be higher?

the BACK of the flange should rest on TOP of the finished floor

The back meaning the ring, yes does rest on top of the floor. So the pipe rising higher is not an issue?

you have a lead pipe with a special brass flange.
our sponsor sells replacement flanges for your application.
the lead needs to be carefully straightened so the old flange will slide up and off. the new flange slides down and the lead is peaned (sp?) over. stainless screws hold it in place.

peened



Packy's description of the flange is correct

you need to take the old flange off and the inside flange will work just fine

I've never heard of using those in a lead bend.

I had a plumber look at it and he recommends not using the pvc flange with the lead pipe, but to remove the old flange and put in a new outside repair flange that goes flush over the tile since the hold is a bit too large. For the crack in the pipe, he recommends a lead pipe "repair collar."
