Loosening Seized Pipe Threads with a Cold Chisel
In this video, I demonstrate how to remove a stuck pipe from a fitting using a saw and cold chisel. This is typically a last-resort method when other methods like heating the fitting or penetrating oil don't work.
Thread sealant recommended for worn or damaged pipe threads:

Thank you so much. Literally just saved me $625. That's the quote I had to remove a pipe. Did your method this evening and popped right out😮
Map gas torch. Heat the fitting and the nipple or pipe a little bit and it will come loose. Don’t burn down your house, very important.
Or.......use two hammers.....place one hammer on the opposite side..... hit the pipe firmly with the other hammer. Do this all around the fitting........several times. Dont hit so hard as to cave the pipe in. Just to loosen the threads. Rust takes up space.......and by tapping on the fitting / pipe it forces the rust to move...give way.......and then use a vice grips or pipe wrench and remove it.
They actually sell cogs that are conic shaped that you can tap into that cut pipe with a hammer and then reverse them out and the cogs bite harder when being reversed out.
Nice. I live on a ranch in Mexico with a bunch of old galvanized pipe that need to reuse,but threads are all broken......i happen to have a sawsall.! Thank you for this tip
In my situation, the pipe nipple was so badly rusted, that it collapsed when using the pipe wrench. So off to youtube, and I found this video. I didn't use this exact method but chisel and hammer and eventually got the pipe out. Thanks for the video, saved me hundreds of dollars on a plumber. Sorry plumbers, not today.
My opinion cutting the pipe that close is kind of dumb, because if chiseling don’t work then want? Use a pipe wrench and use a hammer same thing
I just fixed my water heater drain valve with this method thanks to your video!! Saved me a lot of money
Most of my galvanized kitchen 1.5" sink drain pipes are 60 or more years old with major internal female thread corrosion. A new nipple won't fit anymore. I have an 1-1/2 in.-11-1/2 Carbon Steel NPT Pipe Tap on order, see if that would clean out the female threads.
thanks buddy!!
Thank You Sir! I am getting ready to do some major work on an old galvanized system and this really will help me out!
Great tip. On a side note, I need that adorable reciprocating saw.
