I'm a DIYer, debating whether to call in a pro. Installing a pedestal sink, which interferes with the existing angle stops - the stops need to move about an inch closer to the wall. The stops are on 3/8 chrome-plated (presumably brass?) nipples. See photo link.

The house was built in 1956, and has all copper plumbing (that I can see).

So, my question: if I unscrew these nipples, what are the odds they will simply unscrew, and I can install new, shorter chrome-plated brass nipples, and I'll be happy? (vs the alternative, they will break in the fitting, or the fitting will break, and I'll have a job on my hands that I can't handle...).

On a related note, if I do go ahead, I understand I should use PTFE tape plus dope for both ends of the nipple?

Thanks for any advice/predictions!

on a scale of 1 to 10, yours is a 9.9 success rate.

stainless steel nipples (if available) are just as good and quite a bit cheaper.

Packy,were do you get stainless streel nips?

35 years I have never bought...never heard someone at the supply house ask for them. I've always used chrome plated brass nipples.

even my local ace hardware sells a small variety of stainless nipples.

Packy, I'm just saying I've never seen any Plumber order them...I know they exist. It could be a north shore thing.

yeah, what is the supply house supposed to do? carry a supply of brass nipples, chrome nipples AND stainless nipples as well..

If the risers in the wall are copper, there's a fair chance that when you try to unscrew the nipple, you could rip the copper X FIP elbow off the pipe. I've seen a few plumbers use wing ells in the wall, but not many.

wing ells for 1/2 done most of the time. but wing ells for 3/8 are pretty rare.
