I've just built a loop and have the same problem that a few others have mentioned. The system is water tight, I can run the pump at 100% without leakshield protection and not a single drop leaks out. However, when I turn on leakshield I can see a small bubble getting sucked in every 5 seconds or so. The annoying bit is that it gets trapped in the cpu block. I've actually identified two places in my loop where bubbles appear and both of them had the 180 degree 5-way rotary adaptor - https://shop....
