I used a heat gun to pull an old long inside toilet flange out of an even older flange. I then cut the top of the flange off and am left with a thick PVC pipe measuring 4" OD and 3" ID. I guess this "pipe" is part of the original flange and I can understand it is an odd size but the pipe goes into the slab and down about 12" before there is a joint at a 90, which I'm not sure I understand what size that would even be if the OD is 4" all the way down? The toilet is 14" from the side wall so I really need an offset and it seems like I can not get a inside 3" offset toilet flange, and a 4" outside flange is going over an OD 4.5" pipe and this is only 4" OD. Is there any flange I can use for an offset here?

You may have had a 3x4 inch flange that can either go over a 3 inch pipe or inside a 4 inch pipe.

In that case, if you get to where protrusions are filed off, you could glue a 4 inch spigot closet flange there.
Post a photo. 200kB max. 900 pixels max if you want to upload.

Take the rag out before shooting the photo, and then put it back.

There is about 6-8 inches left till the glue joint at the 90, I am not sure if it tapers any as it goes down.

You could possibly use a 3" ram bit/socket saver and use a 3" spigot flange. Not sure if there are spigot offset flanges. As a note offset flanges are not code approved in my area.

I am not sure what you have there. Did that black have a metal ring around it and you removed the metal?

How recessed is that black? What is the OD and ID of that black?

Your post referred to PVC. PVC for drainage stuff is usually white, and I see no white. The old flange could be ABS, which is a plastic that is usually black.

If you have a 4 inch ID hole, I would consider a 4 inch PushTite closet flange. I would also consider just putting a repair ring, with ears, on top of what you have.

Maybe lay a tape measure on edge across the middle of the black. The tape measure should be atop the finished floor, and I expect a gap under the tape. Then take a photo at about 45 degrees angle, looking at the numbers and the flange area. We will be looking at dimensions, and want to see how much space is below the tape measure tape.

The pipe was originally a flange that I cut off, which was almost 2 inches imbedded into the concrete you can see the bevel it made going to the metal ring in the concrete where it tapers. It also had a replacement 3" inside flange in it also which I took out with some heat. The ABS is 4" OD and 3" ID.

Suppose you glued a short piece of 4 inch ABS pipe outside of what you have. Then put a 4 inch outside flange on that, such as
the Steven Jones Code Blue C40640. It offsets 1 inch. It goes outside of a 4 inch pipe.


The side view profile would have to match.
