Thanks for the feed back. My concer is wheather or not the galvniazed
pipe is welded into the Cast iron? I am certain this is a difficult
question to answer unless you could see the pipe. To pose the
questions better, was it standard to weld the galvanized in to the iron
pipe of should I just be able to unscrew it?

It's unlikely that the joint was welded originally. However,
it probably is now! Thanks to the corrosion.

The galvanized pipe is trouble waiting to happen so I would
get rid of it if at all possible.

I'd be inclined to give it a shot myself but be willing
to back off and call a plumber if undoing that joint
appeared to take the kind of force that could create
even bigger problems (rather likely IMO).


I don't see why the pipe should be any major problem,
esp. given that you can look in the open end and
see how rusted up it is. But if you really
want to remove it, it doesn't have to come out in one
peice.
