How to get bubbles out of your loop..

[Kenjiwing]

I have a decent amount of bubbles at the top of my res.. whats the best way to get rid of them and what kind of problems do bubbles create in the first place?

[Waterlogged]

What type of res? How full is it? Is the cap off?

Generally, bubbles at the top of the res are of little concern as they will eventually disappear.

Its been about a week and the bubbles are still there.

The res is about 95% full and its a inadh 250. I didnt have it full first but the noise of the water dripping from the top to the bottom was annoying so I topped it off. I can take a pic tonight if needed.

I ran my loop on low speed for like a couple of days when bleeding it, also with the cap on the res off during that time. I think the trick is to lower the pump speed to allow the bubbles to follow the path of least resistance so they can escape...someone correct me if I'm wrong

Did you put any funny things into your coolant mix?
I'm inclined to suspect there's some contaminants in your coolant that is causing the bubbles.

Screw res caps on pretty tight and tip your system over each direction practically 90 degrees, do this a few times in a day, after that just wait, if there is no leak then no reason to hurry. Give it time.

If your outlet (on your res) is not sucking bubbles into the loop, you should be fine. Like previous mentioned, is there additives in your loop, cause some additives sometimes create foam or lots of tiny bubbles that accumulates at the top of the water in the res.

Also, have water coming in from the top of your res and breaking the water surface in your res will make you get air bubbles also.

I am using the top port of the res to put the water into the res. The only coolant I used is distilled water with a silvercoil on one of the front ports.

Do you think its because I used the top of the res to put the water in?


Here is how im putting water in and out of my res.

Did you tilt your case while bleeding? I could be air stuck ie. in the rad and slowly bleeding out.

a pic of your loop would help

[Kenjiwing]

Ill take some pics tonight and no I never had it tilted so ill try that tonight.

[jim0ne]

Pics would be great... if you take a cup of water (no bubbles) and pour water in, some bubbles will form. Same concept with the falling water in the res. As i stated before, if the outlet is not sucking bubbles into the loop, there's no problem.

If you have the inlet at the top, and no tube inside the res to lead the water down, then you'll have bubble issues Air from the top of the res will get pushed down together with the water, and sucked into the pump.

I usually shake/tilt my system a bit when bleeding it, I can hear the water swishing in my top mounted radiator.
Reservoir mounted in the bottom of my case, but it forces the bubbles out pretty quickly.
Let it run overnight with just the pump on to make sure the small bubbles are out (made a wall plug DC 12V adapter for this).
Afterwards, no swishing sounds..
