That's what I thought as well, but the plumber showed me a length of
galvanized steel cut out of the middle of a longer length in the attic,
with the hole in it. And pointed out some elbows in an exposed wall
(exposed as part of the renovation we have in progress) that he said
were showing signs of the corrosion, and they're minimally several feet
away from any copper.

So, is this possibly the result of something else?
