Alright, I put this toilet off till last because of the caulking all around the base. I figured it would be a hackjob. The pipe appears to have an ID of 3.5". There is no flange for the bolts . The old toilet had a homemade wooden spacer with the jbolts going through it. That spacer was held in place (poorly) by mortar. It looks to me like what I am looking at is the bell end of a section of pipe? Like it never had a flange to begin with and maybe originally it had bolts embedded in mortar and the wax ring set right on top? What's got me is the pipe size. It appears to be 3.5 Id but the "bell" end looks to have concrete inside it? Like they made a smooth transition to the waste pipe with mortar ? I have put an arrow on it. I'm trying to figure out a way to fix this without tearing up the floor. My original thought was to put one of those expandable flanges that goes inside pipe, then add a spacer underneath the flange and bolt the flange to the concrete subfloor. The pipe appears to be a 3.5" ID vs a 4" though? The pipe goes down about 12" then 90s..it looks like it's all one piece like they stubbed the sweep up and set it in concrete.

who knows what they did back in the day. But hey, it worked for years, right? lol

Maybe you can rebuild it, like something in the video.

Others will be along shortly with better advice.

Yes..who knows..I forgot to add the house was built in 78. I doubt that toilet was original. I think whoever tiled it came up with the wood spacer. It was like an inch higher than the floor too..there was wax everywhere..also it has been leaking for a while, hence the reason for pulling it up.

Your flange...what's left of it appears to still be there. This probably isn't as bad as it could be. I have seen this too many times.

Just watch the 10 minute vid, start at 5:15 if you're impatient. I would place a rag in the hole to prevent materials going down the pipe!

I would blast it out and install new stuff.

Thanks very much for the link. That doesn't look bad, but I dug a little deeper..It appears that my flange is full of concrete, and since I'm on a slab, the outside is obviously concrete. I just worry if I get to air chiseling etc, I'm gonna tear up the old, fragile pipe. Sitting here scratching my head, wondering which direction to go.

Another picture . I guess I can just break out the concrete and try to get the old flange off? Main problem I see would be even if I install one of the new style , compression flanges, there won't be any support under the flange because the concrete would be gone. Would the correct way to be removed the flange , pour some concrete in so it's flush with the tile, then set the flange? I would think the concrete would be so thin it would crack trying to drill it..

I would replace it with this one and just shim with plastic shims under the screw holes.

Your original idea of using the expansion/compression replacement flange, I believe the same one Neal suggested, and the same one Rich Tretheway used in the video might work, depending on the condition of the pipe. I can’t tell the exact condition of the inside of that pipe, but it looks rough.

Here is another possibility that might work if you don’t want to remove the concrete around the pipe. Using a few Tapcon screws and a little imagination might make this workable. HydorSeat Toilet Flange Repair
