Koolance QDC for fill/drain ports on res

[steers]

Hey guys,

So I'm in the constant process of planning and refactoring my loop that's going into my build this fall, and one aspect of it I haven't been able to finalize is what to do about draining my loop (for changing coolant, etc). Initially I thought about making a little T before the inlet of my pump, with one end having a short length of plugged tubing, but I don't think there would be any way to do that practically in the case I'll be using. I've since had the idea to use one of the ports on my reservoir (which will be in the middle of my loop, height-wise) to drain my loop, but I'm kind of stuck on how to really go about implementing this. I'll probably be using an EK Multioption 250, so I could use the bottom port to drain and the top to fill. I came across Koolance's line of quick-disconnect valves, and these look like something that may be perfectly suited for this application.

Has anyone had any experience with these QDC nozzles? Does anyone have any pointers for draining your loop that could be imparted to this noob?

Thanks.

I've got the same res, and here's what I do to drain the loop.



Unclip it from the mounts and turn it over. It works fairly well. I've done the t-line and plug drain before, that also works.


Edit: I can't see my image, sorry. I'll repost it when I get home. I use the top as a fill line, then turn the res over to drain it.

I have never used them, but I have heard complains over leaking for those.

If you have radiator on top of the case draining is easy task, you can have a pipe from the bottom of reservoir. In my new build I have rad on the bottom, so when I was needed to drain distilled water to put Feser liquid I just put case upside down and drained it from the fill port. He-he..

JDRom use's a set on his rad, I know he mentioned they dont leak but about 1ml of liquid spills out when disconnected.

Im using them in my build right now, they are great and they do spill a little liquid when you disconnect them so all you have to do is wrap a paper towel around when you disconnect.

I got Linus to get some into NCIX so us Canadians can get them now

Thanks for the help everyone. It never occurred to me to use the fill port to drain before

I think I'll just end up doing that

Yeah, the VL4's are pretty sweet, and a big improvement over the VL3 QDC's. But you definitely need to wrap a paper towel around them when you're pulling them apart.

I have the VL3s and they work alright but it's a bit tough to get them off. They have a pretty good seal once connected.

And I can't really fathom spending another like $50 for a pair of VL4s...

Ouch, you're not kidding. When I got mine, they were only about $10-11USD, and I piggy-backed the order on some other junk. Those NCIX prices are a little high. But in all fairness, when you compare them, it's pretty easy to tell that the VL4's are freer-flowing, which will always appeal to a certain market-segment.

I have a set of VL3's going in and out of my pc, it's the bracket so when I bring my PC somewhere I just disconnect the external rad from the rest. Quite useful, just need some paper towel when disconnecting.
