Last night I was in a bind and used a 1/2" female coupling along with a 1/2" nipple to extend my bathtub spout connection a little further out from the wall. I later realized it was black gas pipe instead of galvanized. Will this be an issue? Thank u!

Yes. It will be.

yes

the preferred material is brass

however

brass is $$$$$

so make a 'filler piece' using 2 Cu adapters and a short piece

After a few weeks, you'll get a dose of brown rusty water every time you turn the tub on.

Will it rust thru faster than regular galvy?

yes

As always... Thank you for the advice! Like I said,it was late and that's all I had and later realized what I did. How long you think before the black pipe rusts thru though and starts leaking?

10 years or more. But that rusty water will be your major concern. I've had to replace a few black iron nipples on bath spouts before, installed by the homeowner or handymen.
The women folk really dislike the look of brown water coming out of the spout before they take a bath.

Yes, much faster.

It will start rusting as soon as it gets wet.

oh - for - petes - sake

just replace the frigg'ng nipple

YOu mean this post cannot go on for two more weeks?

A $.53 steel nipple is at stake here, proceed with caution.

very funny!! actually, the threads on galvy nipple coming out of the wall weren't in the best shape, so that's why I screwed on a female coupling to it and then a small nipple, and then attached the spout to it, figuring it would be a little more secure.

I bought one of those universal tub spouts which I know realized are junk, with all their plastic adapters, especially when the threads on the nipple you are attaching them too are not the best shape. thank you again, for all your advice!!

...perhaps we need Sum's input...?

No comment.

Absolutely... Drag this little project out forever and talk it to death

not really.. i'll head down to jalapenos restaurant later and have a margherita or two while pondering this thread..

Yeah Packy, those beer taps are dripping and only a plumber can properly repair them...

After a few Margaritas, the black nipple might sound like a good idea.

personally, I like black nipples

The realtor who sold my first house helped her father in his hardware store. When someone asked for a 3/8 nipple, she slapped him.
