is this normal?

post #1 of 9
Thread Starter 
Just need some reasurance with this being my first water build and all.

20130604_212909_zpsf0f27767.jpg

Sounds like there is also a crap ton of air moving through the pump as well. This is about 5hrs into leak testing fyi.

Normal? Tips / tricks?

keep turning it on and off , WITHOUT THE MOTHERBOARD PLUGGED IN!
Shake the case,
Tilt the case
flick the tubes a little bit
take some fluid out and run it without the top for a little (res)

First off, try opening your res to let any excess air out. Sometimes you can hear that there was excessive air in the system when you hear air come out, like opening a carbonated drink.

It also helps to tilt your case at different angles to try to get some of the air out of your system and into your res, but this can be a pain at times with heavier builds and larger size loops. Be careful not to move the air from your res back into your system and make it worse.

That air in your pump can cause cavitation which probably isn't good for your pump, and can reduce / stop water flow.

This is normal. Just "bleed" your system of the air bubbles.

Throw a chain around the computer and put it on a engine stand and roll it down the hill! biggrin.gif
are you can put it on the ceiling of the garage and type pillows to it and use it as a punching bag NUFF SAID! tongue.gif
this all was just a joke haha

Yes this is normal and like everyone said the best thing to do is to stop and start it several times and also wait some time occasionally between starts.. give everything time to settle down and also if possible I have found that it helps to take the top off or put a temp tube in the top of the reservoir. To me this seems to help release the air faster don't know why actually I do but complicated answer and would start another thread just from disagreement.. LOL but I do believe in my answer 100% as hydro thermodynamics is part of my job so I do know a thing or 2 about this. but you did not ask why, you ask if this was normal and it is just takes time...

If you are 5 hours into leak testing and this has been going on for that long then it is NOT normal. You might have a fitting, or fitting plug that is not on tight enough and is therefor sucking air into your loop constantly. I have had this happen to me before when I tightened the plug enough to stop the water from leaking out, but not enough to prevent a little air from being sucked in. Recheck all your fittings and make sure they are tight. That's just my guess, good luck!

Maybe I am just unlucky but it always takes me longer than 5 hours to get all the bubbles out of my loop. Plus got to realize that pictures usually make something either look a lot better than it is or makes them look a lot worse. all in the eye of the beholder i guess.

But even with the simple loop I have been using for testing it takes longer than 5 hours to get all the air out and this is with making sure everything is tight because i am well aware of the venturi effect. the thing that seems to help the most is removing the reservoir top??

Think i figured it out.

The turbulence from the output was creating the bubble storm. Topped off the res and power cycled the pump a few time and the sound went away.

Thanks for the help fellas.
