There is a tool to cut old pipe out of a ABS fitting. Don't think you want to spend that much $$$.

If you have a bad glued in valve simply buy the same open it up and remove the center slide portion and seals and install in old valve.

You can not unglue, You can however cut it and use no hub clamps from your local Home Depot or Lowes. I did this with mine so I could replace the 3" waste valve. Just make sure you cut it straight as possible.

My rig has a flexible 3 inch rubber connector between the 3 inch plastic pieces. Had to replace both of them just after I bought it (The old story... we never used the toilet or the shower) Yeah right. Anyway, each piece is a standard household connector readily available. They come with two screw clamps and are easy to install.

If you just need a valve, no cutting is required.
Simply buy a new valve, unscrew the 4 small bolts and slide the new valve portion in. You'll end up with extra pipe connections that you don't use.

You need something like this: 3" valve

Home Depot sells "Socket Saver" 3" for $13.22
Menards sells "Saver Reamer" 3" for $8.99
Just in case you need one.

I have never seen or heard of a glue in waste valve before?

Mine have always been the undo the four bolts and slip the new one in there. [emoticon]

Something new every day.

That's what I was trying to get them to do in my post. People are hung up on replacing the pipe flanges, which of course is totally unnecessary.
