toilet flange


Any advice on how to redo this toilet flange?
It is cast iron and there is no room for a compression type flange without cutting the tile.
I tried a pvc flange with a rubber gasket, but it sat too high and the wax ring got flattened and it still wouldn't sit on the floor

Go under the floor and cut off the pipe, install a hubless connector. Make up a new tail piece out of PVC and a new flange.

What's wrong with the cast iron, why are you replacing it?

No access under the floor. Right now, there is no flange on the cast iron. It was ripped off when the room was demoed.

Here's some ideas on some repair flanges that would work.

I've looked at many options and picked 2. The first is the one in my picture and it sits too high to work correctly. The second is too large to fit inside the tile without cutting it to make room. Any ideas?

What you got will work, but you got to take an angle grinder with a tile blade and cut the tile so that your push on flange will go down further. Or if it is hitting on th cast iron, you are going to have to cut the tile with the tile blade and then switch over to a metal blade and cut the pipe off flush with the floor. That pipe looks like clay to me because it is so thick. If thats the case cut it off with the blade that you cut the tile with. You are just going to have to be very careful that you don't break it. Cut slow and cool it off with water as you cut if it is a clay pipe if you even have to cut it. If you are just hitting on the tile, just cut the tile and leave the pipe alone. You can use a spray bottle to keep the dust down while you are cutting.

A tile bit in a Roto Zip, a diamond blade in a right angle grinder, Ossilating saw with a diamond blade. Take your pick anyone one of them can cut the tile back.

Joe i don't knlow about that rotozip bit. I have tried them on floor tile and they don't work too well, but they cut through ceramic wall tile ok.

It looks to me like the pipe itself is too high

That's the thickest cast iron I've ever seen. looks more like clay. Cut it down about an inch and use the inside flange

Take a file or grinder and clean a spot on that 'cast iron'--I think the Eplumber is onto something--

Clay tile---you may find that an angle grinder with a diamond blade is needed---they are not expensive tools and mighty handy to have around the house.

You guys are probably right about it being clay. I can actually get to if from the basement, but it is a tight squeeze. What would I use to cut it off? Do I use a fernco (hubless connector and then 4" PVC with a new flange on top? If so, I'm guessing I still have to cut the tile opening larger so the flange can sit flush with the finished floor. Is an angle grinder the safest/easiest way to cut that or is there a correct size hole saw for tile that I should use?

i'm not sure where you plan to cut it, I'm actually surprised it's clay Especially in a basement. Clay is usually found outside the foundation and cast iron inside the house. Anyways, there is a fernco called 4"clay x CI/Plastic. It should work at your transition.
