Air bubbles

Avengersbuild · November 7, 2020

So I started my custom loop,

EKWB FLT 360 Distro plate,

only going to cpu for now until I get my 3080 and EKWB blocks in.

the drain plug on the distro has air bubbles coming in(sucking into it) just noticed it last night.

The issue I see is,

1. EKWB pressure tester and it’s been running for a week have shown no leaks.
2. Paper towel underneath the plug is bone dry. I undid the fill port, put paper towel underneath it for the night and it’s bone ass dry(removed GPU, it’s an 011 and the PS is up night, and the power unplugged)

is this normal? This is my first custom loop. It’s been a learning experience and I have a siphon to drain the plate so I don’t need the drain port.

you can see one bubble take off in the video here.

thoughts? I don’t see any cracks in the acrylic either. But an air pressure test that lasts for hours and air escapes easier the water.
