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.
Thanks for the responses. I guess I need to explain what I have a
little better. Behind the tanks of all three toilets are the ends of
these vents. And I guess I am assuming that these are vents. The
ends are stuffed with rags and haven't been used for God knows how
long. And again two vents merge in the attic and go out the chimney.
The third goes out the roof. I don't know how these were connected to
the toilets back in the day. Surely others must have come across vents
such as these. Does this help at all? Thanks.
Yes, they were installed for venting of room air, rather than as part
of the DWV vent system. Precursor to the modern bath vent fan.
Rather an upscale feature in 1924, I should think.
You could install a sheet (sheet metal or other) behind the
vent grill to permanently stop loss of conditioned air from the bath(s).

Again it is someone using wrong terminology to describe their problem. They
know enough terms to thoroughly confuse anyone who believes the person is
describing a problem with the item they are referring to.
A problem with a "toilet vent" immediately brings to mind the "Drain, Waste
& Vent" DWV plumbing system, where the original poster is describing a
bathroom ventilation duct. It has nothing to do with the toilet other than
being near it to remove smells. Confusion, confusion -- a good thing that
someone finally clued into what the OP is talking about because it made no
sense to me when I read it.
