Cast iron drain pipe

What's the easiest way to remove lead from 3" drain pipe without damaging female connection? Without burning rig. My bottle is empty.

Not sure why you would want to. Just snap it off with a chain cutter you can rent. A 4-1/2 right angle grinder or a sawlsall with a carbide blade will also work, Might take all of 5 min. and leave a nice smooth cut then just use a hubless connector.

sawzall with a metal blade will do it also, trick is to slow the speed of the sawzall, mine has a speed control switch. Is normally on 6, for cast iron use a metal blade and turn the speed down to 3.
I have seen my plumber come in with a old used metal blade and cut out every cast iron pipe in a house he could get to, and blade is still good for the next job.

If you want to remove the lead- use a 1/4" drill bit. Drill several holes into the lead around the circumference. Pry out whats left with a screw driver. Now you should be able to wriggle the pipe/fitting out of the oakum.
sorry for the small image
