Hello,
I recently built myself a custom water loop, and everything seemed to be going smoothly until i had a look this morning and spotted this..

I only have a very limited view of the other fittings but from what i can tell this one is the only one where a very small amount of liquid has started to gather. Could this be the first sign of a very slow leak? or might it just settle there and not do a lot of anything else.
Given that this is my first experience with such things any information/opinions would be appreciated.
Loop = D5 Bay Res -> 360 Rad -> Cpu Block -> Pump
