My son accidentally put a length of
black pipe in his bathtub. It is from
the faucet to the spigot. Now, when you
1st turn it on, you get a small amount
of orange water. I know, in the old
days (very old days) they sometimes used
black iron for water. Is is worth
tearing down the now finished wall to
redo the pipe, or will it rust so far
and quit? He probably will sell the
house in a year or so. Thanks.
Just be happy it is only the bathtub. If it were a drinking source like a
sink, it might be worth it but most people shower or run the tap for a
minute before filling a tub so I doubt it would be noticed. It will
continue to rust but many years will pass before that would be a problem.
I'm not a plumber, but can't you just remove the spigot and take out
the black pipe? I thought they were threaded in the wall and part of
it sticks out of the finished wall,so there is no need to do any demo.

Yeah, sure, if it's not been tiled over.
He did say "finished wall".

That or use the other side of the wall if it's an interior wall.
Yeah, learning this after tile was installed would also indicate there
probably wasn't a permit filed for it, let alone an actual inspection.
Always good to check with the permitting office BEFORE buying a home to see
if they filed the right permits for the work.
I am not sure what pipe you mean. Is it the pipe between the faucet
and the shower head? If that's the one, just leave it. There is only
water in that pipe when the shower is being used and the pipe will
last forever. You'll just need to let it run a few seconds to get rid
of the rust colored water. However, if it's connected to the water
feed from your water supply, you will eventually have a problem and
would be best to replace it.
Unpleasant memories! I had the same experience when installing a Moen
single handle tub/shower several years ago. The installation instructions
say, "Caution, use 1/2" iron pipe for tub drop." This is the vertical pipe
from the valve down to the elbow and nipple that support the tub spout. I,
of course, followed the instructions exactly. Since all the other plumbing
and fittings are copper or brass, I got the galvanic action and lots of rust
in our softened water. Learning of the problem after the installation was
complete, I had to open the wall and replace that piece of pipe with brass
to provide equivalent rigidity.
I cannot understand why Moen would make such a directive when copper
plumbing has been the standard for many years.
Incidentally, if the problem is not corrected, it may produce rather
persistent rust stains on the tub.
