Help- Bleeding custom loop

[pigeonguyuk]

Hi All

im having some issues with my loop. Using monsoon bay res. the system is packed of millions of micro bubbles.

throughout most of the tubing there is like a wee stream of them constantly following the flow direction through my loop.

these then seem to be collecting in my top 420 radiator causing massive air locs leading to only a small trickle leading back to the res.

ive shook the absolut *** outa the case in all different directions. the res seems quite turbalant due to the incoming fluid. the res is nearly at the limit so not underfilled.

any suggestions or advise

Did you open the fill port to let the micro bubbles escape? Are you using a lot of 90 degree fittings? These can restrict flow preventing the air bubbles from being pushed out. What speed is your pump set to?
Rather than just shake the case, leave it in different positions, sideways, upside down, front down, etc.
However you'd need to proceed with caution and ensure the fill port doesn't leak (hopefully has an watertight O ring).


How did you fill your loop? I would fill enough just to cover the pump then turn it on and start pouring slowly, very slowly and allow the air to escape. Pouring it fast and with it switched off can sometimes cause the air to become trapped. I normally do it with the pump running without running it dry and it usually sorts out the bubbles.

Also try temporarily lowering the top rad as low as possible and open the fill port with the pump running. Keep the fill port at the highest point of your loop as the air will always try to escape at the top, which is probably why it's collecting in your top rad. Having the rad higher than the rest of the loop makes it harder to get the air out. My XSPC Dual D5 bay res is right at the top which is probably why I find it easier to get the air out.

When bleeding a loop the aim is not to get bubbles moving. The aim is to get the air into your reservoir and not let it get pumped back into the loop.

Have you got a spare set of ports on a radiator?
When filling my loop the pump does not move the water, opening a port on my front rad releases some air and only then the water moves.
