I need to break a rusted galvanized pipe joint that is used is used for yard watering system. Is there any compound that can be applied to the metal that will make it easier? I haven't been able to get it to move with 14 inch pipe wrench. Next I'm going to try to rig up a cheater with a length of pipe fitted over the wrench handle.

Thanks, Dave

Load the threads up with WD-40 and put a "cheater on your pipe wrench. Good luck, tom

Sometimes you can break up the ancient doping compounds in the threads by trying to lightly tighten the joint first before backing it out.

Try tapping the joint with a hammer. Not to hard or it will break the pipe.
