I had an issue with a leaky T&P a few months ago and I replaced it and I replaced an expansion tank (water pressure was also OK) I chalk it up to a faulty valve. Anyway... I also added a new copper discharge pipe to the T&P with a sweat adapter . When done, I put a small cup on the floor so if it were to drip again I could notice.
Fast forward 6 months later to today...... I found a slightly green oily spot on inside that cup... I think the flux dripped down. There wasn't a bead of water but I stuck my finger inside the pipe and it felt kind of moist/cold and I got the same oily green flux on my finger.
Do you think condensation from the pipe or the warm T&P in a cold basement could cause excess flux to run down the pipe over time?
Just hoping and praying the damn T&P isn't dripping.

If you soldered the joint properly, the heat would have "evaporated" any excess flux.

"Properly" being the key word. If an abundance of flux was used I think the heat from the tank caused the remaining flux to drip down into the cup.

at the very end of the cut pipe there is a tiny bit of green corrosion... like the flux beaded there. But again, I am at odds wondering if I have a leaking tank or if it is indeed flux or condensation since this is 6 months after I replaced the thing!
It was certainly oily like flux though.
Could a tiny bit of condensation occur in an empty pipe or from the warm valve enough to carry excess flux down the pipe?

The pipe and air are at the same temperature, so "condensation" is improbable. Don't worry about it.
