The old shower arm has developed a crack and it's weeping water and
getting worse. I have to replace it before it damages the wall.

I got it unscrewed easily, but what I found wasn't what I was
expecting. From all the descriptions I found on the net and from
looking at the replacement arms available in hardware stores, I
expected the arm to screw into a fitting behind the wall, sticking out
through a hole which can be covered by a flange. Instead, I found this:

A pipe sticking out into the shower. Attached to that is this:

Maybe I have my terminology wrong - which is the "arm", the copper pipe
or the chrome cowl? Anyway, I would like to find a replacement for the
chrome piece to save myself from hacking open the wall. However, I
can't find any similar piece in any physical or on-line store. Can
anyone suggest a source for this piece? Any other suggestions on other
ways to repair this?

*I would try taking the old piece to a plumbing supply. My sister recently
did a bathroom over and she installed a shower setup similar to this:

Look up "shower elbow". Most of the new elbows are 90 degree and might
require your stub out to be shortened a bit, or you could match a newer
elbow with a shower valve escutcheon.

OK! The problem has been resolved! I'll post this for the archives, in
case someone else has the same issue...

I couldn't find the appropriate part in any chain hardware stores. I
emailed http://www.plumbingsupply.com/ with links to the pictures
(they won't take attachments), but their email system strips out links!
They eventually stopped responding to me. I also emailed
http://www.cometplumbing.com/ on the advice of someone here. They
never responded.

So, I called a plumbing wholesale company about 20 miles away. When I
described the piece, the guy knew just what it was, and even had one in
stock! Turns out this is made by Symmons, and they call it the "Nu-
Arm", their model number 301. The part is still in production, but I
don't think anybody uses it for new installations any more. It's just
used to repair old installations like mine.

This is great. I can just screw the new one on and I'll be back in
business. No need to be tearing up the walls just yet.

Thanks to all for your help and guidance.
