My loop goes Pump / cpu wb / 280 ek rad / reservoir / 280ek rad / pump.
So two rads. I'm under the impression air is preventing water to even get out of the res, when I fill the reservoir I have to tilt it to get it to go in the last rad but it doesn't go in the other one. I've tried having the parts kind of like they'll be in the case, having them all flat ona table with the cylinder reservoir standing higher, tried habing the rads on their sides and all sorts of other crazy stuff. There's a point where water simply won't move
I've unplugged the fitting and "tested them" without issues and the parts were cleaned and had no issues either.
I'm really scared right now and have no idea what's going on. So back to what I suspect might be an issue, does my reservoir position in the loop pause any kind of issue.
The reservoir needs to be before the pump. Once water gets to the reservoir, it loses all pressure so it won't be pushed through the RAD. Because of this, the pump is forced to try to suck water through the RAD. These pumps aren't designed to do that so instead it will push some water, air pockets, and even possible vacuum pockets. The air and vacuum pockets can actually damage your pump as well as anywhere in the loop with bends.
