Water line corrosion question (infosec.pub)

I live in a condo (40ish yo) and recently a neighbor in an adjacent building had a leak and the board suggested that everyone have a plumber come inspect their units. I just inspected and found various levels of corrosion at most joints with the included photo the worst looking of the bunch.

How concerning does this appear?

the color and corrosion is from the acid paste/flux used when soldering copper. whoever did the plumbing didn't wipe their joints at all after soldering. piss poor plumbing.

source: plumber.

edit- the joints look fine, although kinda hard to see. you wanna look for small damp spots/discoloration on materials under the piping and keep in mind some of it could be from condensation if that area is subject to draft. copper piping will last hella long time if installed properly and seeing how yours is supported by iron nails(suboptimal), i don't think this plumber gave a shit

supported by iron nails(suboptimal)

Is this because the iron and the copper could react to each other? Should it be copper nails?

[–] atlas@sh.itjust.works 4 points 1 month ago

yeah it reacts with iron; normally all copper is to be hung with either copper plated or epoxy coated materials, and taped/covered wherever it may come in contact with iron/concrete.
