I'm putting a bathroom in my basement, and had a plumber come in and lay the PVC pipe after I cut out part of my floor. After pouring new concrete, he came back in and said there was a problem with the pipe for my toilet and it was too high. He said it must have shifted somehow (it did not -- it was like that from the beginning and my ignorance didn't know it was incorrect).
Short of breaking up the concrete and re-running the pipe, is there anything I can do to make this work properly?
Here's what it looks like. You can see the collar of the elbow sticking a good two inches above the concrete.
