How to bleed?

[rack04]

Can anyone provide some sort of guide to the best way to bleed a system? I am trying to learn all that I can before venturing into watercooling. I figure this way it will make things easier when all the parts are lying in front of me. Thanks.

One of the popular ways right now is an air trap. This is a link to one a forum member has made -> Air Trap.

dont be afraid to deviate from that design and choose your own parts. i spent an hour at the harware store fitting pieces together until i was happy with mine.

I just use a good 'ol fashioned T-line. Simply put the "T" fitting right before the intake of your pump and use a funnel to fill the tube attached to the 90 degree part of the "T". Keep adding water till the system is filled. Then let the pump run and the micr-bubbles will slowly work their way out of the system. When the T-line tube gets low on water, fill it up again. It can take several days to work out all of the air in the system, but you can run your computer immediatly after you fill the system.

Is this how it is typically done with a reservoir system?

A reservoir shouldn't need extra hardware to bleed the loop.

Air trap or T-line? The Air-trap doesn't need a resivoir and neither does a T-line. The Air-trap bleeds the system very fast, but it impacts the overall flow of the system as well. The T-line bleeds slow, but doesn't impact flow much. It is also possible to submerge the pump in a bucket, bleed the system in the bucket, then close the system under water. Using this method, you have no resivoir OR T-line OR air-trap or Any opening in the system at all.

You'd still need a reservoir or T-line to keep the system full. Water will, however slowly, evaporate out through the tubing.

Someone on these forums tried that method and reported their system didn't need to be topped off, even after 6 months of use.

I guess I'm just confused on a method to remove all the bubbles from a reservoir system.

With a resevoir, all you have to do is shake the system and maybe turn it over on itself a few times and the air should bleed itself out of the res.

I'm using a bay res and never had to shake anything. Was I lucky?

 

[Cyrix_2k]

I guess so. When I had my bay res, I had to tip my PC on its side inorder to bleed it.

 

[RedViper]

What are you using now instead of a bay res?

T-line

When I get the chance I'm going to add water-tight valves before and after my pump. They're cheap so I'll buy 3 sets. This'll let me construct a meatball F&B set on the fly.

The valves are here.

I don't understand how anyone who has secured their HC to their case could bleed the system withOUT tipping/rotating the case. The HC is a maze of pipes and air is bound to get caught in the tops of the pipes. Am I missing something? I just filled my system for the first time the other day and my res. is connected to the inlet of my pump, and bleeding was awful - I had to tip the whole damn box on its side and all these crazy angles, and every time I would get more and more air out of my HC (2-342).

I can't imagine an air trap would help this either, since the problem is the Hc, not the random bubbles.

any ideas?

Drill a hole in the top tank of the heater core and put a bleed valve there.
