Galvanic corrosion?

[borisf]

Part of our house has been re-plumbed but part still has galvanized piping.

Last week. we noticed a small leak from a shut-off valve in a bathroom vanity. Yesterday, we had a pro come out to fix the issue. He diagnosed that the galvanized nipple between the in-wall plumbing and the shutoff valve had corroded at the joint to the shut-off valve.

He replaced the corroded galvanized nipple with a new copper one. Put on teflon tape and pipe dope. No more leak. Great!

But... last night I remembered about galvanic corrosion.

Should I be concerned enough about the copper nipple tying into the galvanized piping in the wall to have him come back out? If so, what's the best way to address this? Replace the copper nipple with a galvanized one or a brass one? Clearly this isn't an emergency but I want to make sure the fix that I just paid for is a long-lasting one.

Thanks!

long term like 6 monthes or a year is fine as is galvinized but . brass is permanant plumber probebly didnt have a nipple or a threaded anglestop is my guess.
