My toilet was leaking a bit from the base so I figured maybe the wax ring needed replacing. I took the toilet off the flange and saw something that doesn't look quite right. The flange is case iron and one side is torn and coming up. But even worse the flange is not directly over the pipe. It looks like it was pushed a few inches toward the wall. Have a look at the pics:
Here is the front of the flange, clearly not flush against the floor:
Here is a top view. You can see the flange is not directly over the outflow pipe anymore:
Here it is from the back. You can see the tear in the flange:
I'm not sure how this happened. It looks like the flange was pushed toward the wall at some point. Or the pipe was moved out from under the flange. A few years ago we had our foundation leveled, which tends to move things around in your house. That's the only thing I can think of that might produce and affect like this.
How do you fix this? Do we have to replace the tile and move the flange back over the pipe?
