Leak Testing

[Artemis]

Question about the Alphacool Leak Testing Tool and testing the loop. In the manual it states:

Wait 15 minutes and check the pressure indicators. If the pressure decreases by 0.1 bar or more, your circuit is leaking.

I tested the complete loop and in 15 minutes it's not showing a drop in pressure but when leaving the pressure overnight (about 10 hours) the pressure dropped about 0.15 bar (0.5 bar to 0.35). Is that acceptable and if not what is acceptable?

you should probably be alright if the pressure didnt move for 2 hours you probably ok for water

I once dropped about 0.1 - 0.2 bar after 10 hours but there was absolutely no sign of water leakage. Turns out it was the temperature drop at night, causing a slight drop in pressure. If you don't see any water leakage and the pressure is stable for the first q5 minutes, you can rest assured.
