I was putting new toilet and I cracked the flange. the pipe is on the bottum floor and is concreted into the floor under till. Does it screw in or glue in. does anyone have any suggestions on what to do??
We cannot tell you because we don't know what the flange, and pipe, material is. But if the flange broke, then it was because it was ready to, not because you installed the toilet.
From what I read, if you take a hacksaw and carefully cut through the flange to the pipe in a few places, you can peel the old one off and clean it up and glue in a new one.
