Bleed-friendly loop design

[ramthor]

I'm new to water cooling but I'd like to try it. I've read about it extensively but it seems like still not enough. I can't understand how to design a loop that contains an U-shaped tube and is also easy to bleed (flush?) without having to turn the whole computer from side to side.

If you put the drain at the lowest point in the loop everything will drain apart from the content of the U which you have to turn on its side to drain it. Is that how it works or am I missing something?

thats pretty much it, even if you have a bleed valve in place your still gonna have to evacuate the water from the blocks and radiators. I basically blow air through one end of the loop to force air out after tiling the case a **** load.

Im gonna be doing an experiment in the next month or two with using a small airbrush compressor to do the blowing part at a low PSI. but im gonna do that with some test kit and not my live rig, cos im not that brave!!!
