Re: Green lines
Chinese drywall turn the copper black, not green, although I did not rule that out. Units were built in 2002.
This was the only place in the unit that this has happened. I did check all of the wiring and nothng was black.

Re: Green lines
Something has accellerated the corrosion process slightly.
Herre's the color chart for judging the age of copper by its patina.
