Yes, you do risk breaking it. As the other gentleman wondered, wondering if
what you have is a drip leg. Hmm.

In any case, the answer is two pipe wrenches. It also sounds like you're not
really familiar with working on black iron. I'd suggest to find a more
experienced worker for th is job, so you can get some practical training.

Im trying to hook up a gas dryer (Electric's Motor is shot). I have a
1/2" threaded black pipe near my hot water heater thats capped off,
unfortunately, the cap is very rusty, and im worried about damaging the
pipe trying to remove it with a pipe wrench. Any tips for getting the
rusty cap off? Would I risk damage if I applied too much pressure to
it?
