How to Remove Broken Off Shower Arm ?

Had to remove 1978 shower arm. Was leary but did it anyway, and broke it off with half of the old arm threads still in pipe. Pics attached.

Shower is newly restored ceramic. Donít want to damage it. Shower arm plumbing is in exterior wall. Wall is brick veneer. Need to figure out how to remove the broken off piece. Have sprayed it with PB penetrant for now.

Any help will be appreciated.

The nipple extractor will back it right out if you use it with an impact driver and a socket, on reverse. And won't ruin the threads. You have to push in hard on the impact driver for it to bite and back it out.

There are two ways to remove the broken piece. Once is to use an extractor tool.
The other method is to make a small slice in the pipe and peel it out.

Still working on this. Have tried:

Half can of Liquid Wrench.

Nipple Extractor - shank is too short. I think long shank extractor might work. Just ordered one of these. Long Shank Extractor

Internal Pipe Wrench - does not have quite enough bite to stop from sliding around.

Hacksaw and Dremel Grinder - don't know what this arm is made of but I cannot hardly cut it on the workbench, much less in the pipe.

Any other ideas?

It's tough because as you try to expand something inside the pipe it can expand just enough so that it won't come loose. I thought most of those arms were brass.

Your best bet is a close cut hack saw. You need to slice the pipe until just before the threads and then peel it out. I know.... easier said than done.

Nipple Extractor - shank is too short.
I don't quite understand this. Shank is too short? It's either the right size or it isn't. Nipple extractor come in different sizes (diameters) You should be using the 1/2" nipple extractor... on an impact drill... with a socket adapter... and a socket on the end of the nipple extractor. The impact drill gets set on reverse, so that when it bites, it backs it out.

If you push hard enough, it will bite. If it doesn't bite, you aren't pushing hard enough.

X,

I understand that, but my extractor is not long enough to work. I have ordered this for delivery tomorrow.

Long Shank Extractor

Thats what the socket and socket driver adapter are for. You could put a 12" driver extension on it if you needed to.

I understand that too. My remover (actually a BOLT remover) is not long enough to reach the broken off pipe piece (the remover bolt head is too big to fit into the wall hole and, for now, I don't want to attempt to enlarge the hole in my brand new ceramic), so there is no point in putting a socket on it.

I think the tool I've ordered is going to work.

Had this occur years ago. Was told to use a ******* file inserted into the end of the remaining broken threads. Tap with a hammer so file edges will bite into the broken shower arm, then back out by using a crescent wrench on the file. Couldnít believe how simple and quickly it worked. The ******* file metal is hard and edges are sharp it is slightly tapered so fit into the broken piece and locked into it easily with the hammer taps. Not the most sophisticated but cheap and effective.

The missing word is the name of the file. Also a swear word for a fatherless child. Not meant as a slight.

SUCCESS!
Took less that one minute to remove broken pipe with this tool. Insert, tap a few times, unscrew.
Worked first try. Thanks to all for your help.
