I replaced a bath tub spout with a Danco spout made to replace the old
Moen spout.

I made a big mistake by cutting the 1/2" copper nub coming out of the
wall to less than the minimum called for. The minimum length of the
copper tube distance from the wall was 1.5", I cut it to 1". This
resulted in water coming out of the back of the spout when I use the
shower diverter on the spout.

As I see it I now have two options to fix the problem

1 to remove tile and cut through the backer board remove and replace
the copper nub by soldering a longer copper tube to replace the
shorter one

2 cut out a piece of plasterboard behind the plumbing to gain access
to the back of the plumbing and remove and resolder a longer copper
pipe

My questions:

What's the easier option 1 or 2 ??

Am I missing another option that would be simpler?? (NOTE I can't
solder a coupling and a copper tube section to extend the copper tube
from the wall as the coupling would interfere with the spout
installation, not making it flush to the tile)
Thanks for your help!

I may be way out in left field here, but is there a butt joint for copper
that will fit INSIDE the pipe?

I've not seen one, but if the OP can stand waiting a week or so and will
cover the postage (which just went up again today BTW) I'd be happy to
turn one out of a bit of scrap brass for him if he emails me about it.

There is a commercially made coupling that fits inside of 1/2" copper tube.
You will not find it at most big box stores, probably at a plumbing supply
house, they are hard to find.
I had used one in the past but cannot remember where I got it.

You may be able to locate some 1/2" outside diameter copper tube that will
just fit inside a 1/2 inside diameter copper plumbing pipe. A little
soldering and you are back in business without tearing apart any walls.

I think we really need a pic here. Would it be possible to desolder
something and put in a slightly longer pipe?

Another thought...If the spout firmly attaches to the remaining stub,
but leaks because the stub doesen't go far enough into it to connect
with some seal ring.....Then, maybe you could use some silicone caulk
liberally applied in the right place to seal the stub to the inside of
the spout. The water pressures there aren't all that high, y'know.

If you go that route, give the caulk overnight to set before succumbing
to the temptation to test it.

HTH,

Jeff

Of those two options if the backside wall is just wallboard and paint
(as in not papered or other surface) that is far simpler than the tile
route most likely. OTOH, _IF_ (the big if ) you can remove the
existing tile w/o breaking it, you could reuse it and there would be
no noticeable repair area if you're very careful about cleaning up and
realigning everything when you put it back.

Other than the slip coupling no great ideas other than what is suppose
to be on the end of the copper to mate? Not seen a spout that would
expect just a stub piece of 1/2" copper as the mating surface against
the inner gasket as that is a sharp and very narrow/thin edge which
doesn't make much of a seal endwise -- or is there an o-ring around
the outer diameter on the inside of the spout that's the seal? That
seems pretty minimal seal for the water pressure when the diverter
valve is closed, though...can't envision the connection to know what
would be a workaround...

You could get the other style of spout that connects to 1/2" MIP
rather than to a bare stub (nub). This connection is usually at
the far (from the wall) end of the spout leaving you plenty of room
for a solder (or even compression) coupling near the wall.

Also, are you sure the stub is soldered into something behind the
wall? Often there is a threaded elbow there.
