the pipe coming out of my boiler was leaking last year. gotta fix it before i fire up heat this year. i cannot get it loosened. i have used a liquid wrench type product and i suppose i will try heating fittings. any suggestions
Yes normally I take the sawzall and cut the pipe off leaving about 3/4 inch from the joint. Then cut perpendicular across as close to the threads without cutting into them. Squeeze with channel locks it's out.
