I used to do this with brake line fittings that would not come undone.
However, propane never worked well because it apparently wasn't hot enough.
OxyAcetylene worked real well - heap that puppy until it glows, let it cool,
hit it with spray lube, and it comes unscrewed just like that. Not so sure
you want to heat your plumbing that hot - might burn down house :P


If you heat it enough to ignite the sewer gasses, a large flame will
shoot out of the vent pipe on the roof. Not too much problem for a
cast iron pipe, but if the vent is PVC, call the fire department.

By the way, you cant unscrew an old plumbers wife either......
