I'm removing a flush toilet, with the plan to put a composting toilet in its place. The old toilet was short but elevated on a small platform. The new toilet is taller, so I'm removing the platform.
The drain pipe is black plastic. I assume I can't disassemble it at a joint, but must instead cut it with a hacksaw. Is that correct?
What's the proper way to cap the pipe? Maybe some day I'll want to put a flush toilet in again, so it needs to be suitable for doing that.
