Hello. My house was built in 1924. Originally the three toilets were vented up to the attic and out the house. Due to upgrades over the years these vents are no longer in use. Two vents merge into one and runs across the attic floor and into the chimney. I would like to remove it. Is there any reason why I can't or shouldn't? Also should I plug the opening at the chimney and if so with what? I thought I would either a) fill it with foam insulation, b) fill it with mortar or c) crimp the pipe and tape it off with aluminum tape. Any thoughts? Thanks much in advance.
