How do you drain the loop?

post #1 of 10
Thread Starter 
Since my watercooled cards are idling at 40C and load shutdown due to 97C, I am going to need to drain my loop and reseat my fittings on the bridge.

Does anyone know what the most effective way to drain the loop is? I don't want to get anything wet.

I have a 150mm reservoir and a couple of long tubes. I'm scared redface.gif

Uninstall the entire LC system and drain it.

Hi. smile.gif

Hopefully one of your loops "legs" will extend beyond the perimeter of the case, generally the pump will.

If so extend that leg of the loop outside of the case and pull the tubing off of the fitting. Have a bucket underneath to collect the fluid and some absorbent rags surrounding the components just in case.

The loop will not drain fully, but once the initial draining is complete you can tilt the case about to get more of the liquid out. There will be some air-pressure that will hold some of the liquid in the loop, tilting should allow most of the rest of the liquid to drain.

Once that portion is done I generally fold the open-ended tubes and zip tie them, then start to dismantle the loop components that I want to.

Covering the components with paper towels or absorbent rags never hurts.

No drain line eh?

From the lowest point of your loop. I actually undid the screw on the bottom part of the bridge and used a section of pipe cut in half and channeled the water into a bucket, then just rocled everything about. lol..a buddy of mine used a shop vac and vacuumed the water out by placing the hose on the top of his reservoir..this was after he drained most of the water out already...he disconnected his top rad to allow air to be pulled in.

Yeah my loop doesn't really have much room to do move anything out. Either unscrewing one of the radiators on the top of the case with a bucket nearby or taking off a plug from the bridge seems to be my best bet.

Only thing is, one side of my case has no real components on it. Just the PSU. That's the side with the pump and the reservoir and a radiator so I don't know what I want to do yet. Does the water spray everywhere when you're unscrewing like a hose that's on when you're putting the nossle on? Or does it just leak down?

With your setup it shouldn't be hard. Just first drain your reservoir by opening the top. Than put a big enough bowl under your res+pump combo. Disconnect the outlet tubing. That should be enough to drain. You may have to tilt the case a bit if that line is not lowest part in your loop. But as far as I remember from the video it was.

And no it won't spray or anything like that. Just make sure you have a bowl right below.

It did when I first disconnected the tubing connected to the pump...from the plug on the bridge, it'll start dripping really quickly...then turn into a stream. just be ready for it. (it won't fully drain the loop, but it's a good start)

No, the liquid won't "spray" as there is no active pressure, only gravity at work.

You might be able to pinch the end of the hose as you remove it from the barb thereby keeping the liquid in the loop until you have a small bucket or container to collect the liquid.

You might consider removing the PSU from the case and then go about draining the liquid from the loop.

Without a drain line you will have to place some kind of bucket underneath some part of the loop and unscrew a fitting / plug.

REMOVE the PSU power cords first please smile.gif.

If you spill water it is not harmfull but you need let it dry 100% before adding power again.


Another idea would be unscrew the res top. Put the end of a (long) hose into. Place the other end below the computer case. Suck on the end until the tube is fiill with water and let the rest siphon out into a bucket.


When redoing your loop add a drain line. Bitspower make a manifold/splitter when you can run the drain line off. Fx at the lower fitting on your SLI bridge. I can PM you a photo from my build log (the photo is not yet posted there).
