I was wanting to remove a chimney that is no longer in use in my home and a plumber thought that the pipe in the chimney was transite pipe that was used for venting the old HVAC furnace. Can i remove this pipe myself? If it comes apart at the couplings with no demo i should be fine, but if i have to cut it or break it thats another story. Can i wet it down as i cut/break it up and plastic bag it? yes and where a resporator.
