Hidden steam riser

Bill_chicago

The attic in my house was finished (carpet and drywall) before I bought it and I found a capped off steam riser buried in a wall.  I was going to pipe this out so it could be used on a radiator and was wondering if any problems would arise if it was piped out from where it comes through the floor to a place about 10-15' away.  The pipe would have to make a few 90 degree turns, would this work ok as long as the pipes were insulated and pitched back to the riser?

Maybe

It depends on the size of the radiator you are supplying and the size of the pipe. The odds are this riser is also feeding another radiator. The extra condensate may be an issue for the radiator below it. Pitch and insulation are key.

1 1/4"

The supply pipe is 1 1/4" and  the radiator needed for this room would be pretty large.  There is definitely another radiator on this riser on the floor below.

Similar situation

I had the same capped off riser in my unfinished attic. It was piped by the builder. It was also not connected to the steam main in the basement. Just found the other end of the riser in the basement by accident one day.

Check to see if yours is connected.

Its possible this hidden riser of yours was piped in for future use. That's what I had.

Riser

The pipe is connected to the main, I uncapped it and turned on the boiler and air started coming out within a few minutes.
