I'd like to try unscrewing a section of 1-1/2 inch galvanized pipe from a vent line inside a wall, but not if there is a high risk that it will break off at the threads where it goes into a heavy, probably cast iron, elbow up in the wall, as that would make the reconnection of the new vent plumbing more difficult. These pieces have been together for 55 years. What do you think is the chance that it will unscrew successfully and not break off? I'm look for some people with some experience with this. Can't use any flames to heat the ell.
I can get plenty of force on it to turn it from the basement level. I've already put quite a lot on it with no effect, but I can up the force with essentially no limit.
