Guys
See attached pic. This pipe used to serve a (now removed) hot water cylinder. It was cut by heating engineer and for 2-3 weeks not a drip. I then painted some of it as you can see, just some left over silk emulsion. Next day, a solitary bead of water on the end but nothing dripping on to shelf. Dried it, next day, again solitary bead of water hanging off the end. I stuck my finger up and the pipe is wet inside. As I say though there's a shelf underneath and I'm not seeing a small pool of water so it's like it gets as far as one bead of water but it doesn't fall!
Is the tap at the top seeping water or can painting copper pipe cause some sort of condensation, hence the daily bead of water? I'm thinking of just putting a cap on the end.
