what do you mean by galvanized pipe? actual schedule 40 heavy pipe or galvanized stove pipe like for a dryer?
i just saw one last month that was from the bathroom exhaust fan. it was tied into an active chimney. that is a no-no.
in any case, if it is a furnace or water heater vent it is the wrong pipe for that application.
if it is a bathroom exhaust vent it must be directed outside.

In the basement its cast, then It is a thin metal type vent like dryer vent in the attic. . It looks like it just tied to sewer line in basement. It's just acting as a vent. Not sure why it wasn't just tied to one of the other 4"cast vent going through the roof. Maybe they just didn't want to cut cast to tie in. It was done 75-100 years ago. New buys inspection is questioning what it is. I'm thinking it's not code today but was acceptable back then?

if it does connect to a cast iron pipe in the basement, it is not code today nor was it code ever..
no one can tell you what to do with it to bring it up to code until it is known for 100% sure what it connects to on the other end.

Just goes to show why MA requires plumbers to do plumbing, so that doesn't happen anymore.

KC, if this was done 100 years ago then there probably was no law forbiding homeowners from doing their own work.
anyway, if it lasted 100 years, who can argue with the quality of the job.. :>

It's an early version of a catalytic converter. It burns off the sewer gasses.  All the birds in the area have their tail feathers burnt off!

Nothing you have told us is of any value to try to figure out WHAT the pipe is or WHY it is connected to the chimney, or actually, what kind of pipe it is.
