Bleeding swiftech mcres v2

[geoc]

Well, the bug has bit me again, and I am doing a new loop for a computer that doesn't even exist (i'll buy parts for the loop later).

Right now I am having issues with the swiftech mcres v2, it seems like that all the bubbles that get pushed out get sucked right back into the pump. I have left the loop on for hours, and large bubbles are still circulating through the loop(you can see them zip by in the tubing)

There is very little flow restriction in the loop as well, so no bubbles are getting trapped in the rad or whatsoever.

I am using the 2 middle vertical holes for the nozzles, with the lower one being the outlet to pump.

I don't have one right in front of me to verify, but I believe the lower hole points towards the plastic difuser (there's an internal plastic "shelf"). If that's the case then the lower hole should actually be your return so that the bubbles hit up against it.

I switched nozzle orientation, and still to no avail.

There's a lot of turbulence and sloshing inside the mcres and even when filled it up. It acts nothing like the ones people posted on youtube.

What so you have for the rest of the loop? Do you have a way of slowing down the pump speed?

MCP350 w/ EK-DDC X-TOP v2, mcr320, unknown wb, and the mcres

You have too much flow. Slow down the pump somehow or add more restriction to the loop. Not much else you can do. The MC-Res is already the easiest small reservoir to bleed that I know of.

Too much flow? And I was thinking of turning it into 18w.

Any suggestions as how to restrict flow?

The easiest would be to get some sort of fan / pump controller and slow the pump speed to get it bled fully.

Another option, if possible, would be to put a sponge in the reservoir. One similar to the ones used in the Swiftech MCP35x tube reservoir. Not sure if you can get a sponge to fit in the MC-Res though.

simple cheap solution use a pair of needle nose pliers

on the pressure side of pump by pinching the outlet hose closed . this will slow flow enough to dispurse bubbles, once done remove pliers and your set to go.

if bubbles still happening after this operation then cavitation issue

Thanks guys, I finally managed to get it bleed out all the bubbles. Funny enough, it took less than 15mins to fully bleed once I got it going.

Anyways, I decided to mod the pump to be switchable 10/18w. So I choose high power or low power whenever I want.
Unfortunately, you cannot switch the power on-the-fly, but you have to shut off the pump first ( I assume the microproc detects the signal at power up)

Here's a pic: (and Varroa, your pump is in good hands :) )
