in Strictly Steam
A 2" STEAM PIPE RAN FROM MAIN IN BASEMENT THREW ATTIC AND BLOWS STEAM OFF OUTSIDE.
ANYONE SEE THIS BEFORE??

    Possibly a vent line routed outside rather than venting off in the basement.

    Need more information for better answer; type of system and pictures of near boiler piping would help a lot.

    My bet is that it isn't a steam pipe, but the vent from the dry return(s). Not that uncommon in some of the vapour systems, and works very well. Provided, of course, that the rest of the system is working properly! Very low pressure. Traps or orifices all good. That sort of thing...

    In other words, steam shouldn't come out of the pipe correct?

    Keep in mind that when venting, the air will be quite saturated, so what you are seeing may be the saturated air condensing due to the contact with colder air, and not really steam , but condensing vapor.

    Let's not forget the post about the guy that had a main vent that the plumber "moved out side for safety reasons" rather than replace the vent.

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    Does that pipe look as old as the rest of the system?
    There were some early 2 pipe systems that utilized the masonary chimney to assist in drawing the air out of the dry returns. Do you still have a brick chimney or has it been replaced by a "B" vent (if gas).

    However I can't imagine someone recently (20-30 years)installing a new vent and adding that pipe up to the attic.

    If we could see where in the basement it is connected then the reason might be figured out.

    And if it was venting humid air in cold weather it could look like your clothes dryer vent does. IMHO
