Pressurized fresh water pump triggered every 2 hours

We eventually found the leak in a remote area, due to the very small pool of water that was trapped in a corner of that locker. Suggest you trace all piping, starting with the hot system, looking for a similar tell-tale.

Good luck with the detective work!

I had exactly the same problem also near my hot water heater in hard tubing. Only found the mist because I was doing something else and my hand passed across it and then felt damp.
