This morning the threaded end of the shower arm broke of in the wall pipe. About 1/2" or so is still in the pipe.

Is there a way to get that out? I obviously don't want to mess up the threads on the wall pipe.

This image shows what the arm looks like:

A pipe nipple extrator will usually get them out.

I use an internal pipe wrench made by Wheeler Rex.

Our sponsor sells one that is similar, looks to have a bigger shoulder which may prevent it from going in far enough to grab broken piece.

Good Luck.

Oops. Looks like the extractor I posted will not work on shower arms because of their thin walls and larger ID.

a 'swivel cam' extractor will work

EDIT:

Curly and I stand corrected: Because of the thinner wall an internal cam type extractor may not work on a shower arm.

Perhaps it does not work on all shower arms.

The following is on the same page Curly linked to, at our sponsor's site

Q. "Why won't the 'cam style' internal pipe wrench work for shower arms?"
A. The "cam" style internal pipe wrench works by swiveling the cam as it is turned inside the nipple until it wedges the cam and the non-swiveling part of the wrench against the inside of the nipple, locking it into place. Since shower arms are normally made out of a very thin walled brass pipe, they have a larger inside diameter than normal steel or brass pipe. The swiveling cam will not normally be able to reach the inside wall of the pipe enough to wedge itself and grip the internal pipe wall for proper locking action and removal

I use a "three jaw" expanding internal wrench.
