Gurgling Sound in Water Loop

Recommended Posts

Posted · Original PosterOP

I just built my first custom loop. I'm proud to say that there are no leaks. How ever I hear the sound of gurgling water. I believe this is due to air within the loop and I need to bleed it out? How exactly do I go about doing that? I opened the caps at my radiator and fluid came out a little so I closed them back up. The sounds seems to be coming from my radiator though. Thanks for any help.

This is why people like quick disconnects.  Lacking the ability to do that,  How do you feel about picking your whole machine up and holding it in weird orientations?

I could if necessary. Just simply tilting it won't work?

Depends.   There can be a problem because of the reservoir as well.  There are various tricks.  I just kind of like that one because people look so stupid when they’re doing it.   There’s also the slow method of just running it and waiting.  Can take a loooong time.  Or not.  It’s kind of random.  It’s a big enough pita a lot of effort often goes into avoiding this issue.

How do I go about avoiding it next time I fill it up. So I run it for a long time and wait for the air bubbles to go to the top of my resevoir and then just *top it off"?

Yep.  If there’s air gurgles there’s a waterfall so small air bubbles will be mixing and the air will be pulled out bit by bit by the flowing water.  Could take days.  Or weeks.  Or minutes.  One never knows.  There should be numerous videos on the subject.  LTT should have some good ones.  They’ll likely be older.

I just turn the pump to max and tilt the case around.

So I left the system running, and it worked no more gurgling sound, however now I have air pocket in resevoir. Do I have top it off or is this unnecessary? And do i do this with the pump on or off or doesn't matter

I would recommend you to top it off. Does not matter if pump is on or off.

A couple tricks

Rotate the system 90 180 450 360. With a little shake in each position. 

 If soft tubing.

You can:

Do the same 

Or

Squeeze and release the tube after where the noise is coming from( the tube after the pump in your case) or the highest tube in the loop but before the res. If the res has a port that can be open without leaking it would be recommended.

Just like bleeding air when filling a car engines cooling system.

In my experience it just takes time. I usually just leave it be and in about a day it sorts itself out.

 

Small bubbles keep being sucked in by the pump and it takes quite a while for them to actually float past the intake.

In my loop I have to set the pump speed slightly lower so it clears up faster.
