QD as Drain Valve

post #1 of 10
Thread Starter 
I'm trying to install a drain valve on my basement XSPC EX240 Multiport Rad., that's in my Corsair C70. A ball valve in the closed position won't work due to PSU clearance issues, so I'm considering using a QD as the valve instead.

I plan to have the QD male attached to ZMT tubing coming from the midport 90, but I'm concerned about long term leakage if not attached to the female end. I wouldn't use the QD female/ barb until it was time to drain the loop.

Thanks in advance.

Uh, we're talking no -leak QDC here?

A simple tube + marble is surprisingly effective though.

Any particular marble color work better than another wink.gif

That's a very personal choice.................

You'd really have to visit some marble stores and get an idea of what's available and the price ranges. Perhaps they will even have "loaners" that you can take home and try out., Then, armed with that, you can start looking for what you have at home rolling around in the back of drawers or stick in couch crevasses. I know they're illegal in marble games but how about a ball bearing? Then there's always rocks you can find in your back yard.

I know that in a few weeks and for less than $100 you can find a "keeper".

Good luck on your searching..................

If you can't squeeze typical ball valve then use classic seal plug like this one.

It's perfectly simple and solid way of making drain point. I would advise against using QD for draining. Especially in very tight spaces (it can disconnect on its own if there is too much pressure from cables or case frame or whatever)

Or perhaps use small ball valve. Phobya making some of those which are much smaller and less robust than anything from Bitspower, EK or Koolance (all of them are massive, high flow, behemoth valves). Using them frequently in tight spaces (like drain between 2 pumps) where nothing bigger fits.

I am using this on either side of a QD for the build I am currently working on. Then, during maintenance, my hope is to put one end in new fluid and the other end in a drain bucket to do an automated flush of the system. Even if that doesn't work, these are small and easy to use for draining.

Actually, I was considering sticking a .40 S&W in the tube end because it's 10.2 mm in diameter and the brass case would make it easier to remove when draining smile.gif

You're going to need a Founders Edition marble for this.

That's a great idea thumb.gif

I also thought about just using a F-F 12mm Extender and plugging the end but the Aquatuning 10mm (3/8") tubing adaptor would be cheaper.

I also considered the Phobya and a similar one from Alphacool, but their handles are longer on one end, so in the closed position it would butt against the Rad shroud or the side panel depending on how I installed it. I only have about 38mm between the Rad shroud and the side panel, so the Bitspower MVV and the Alphacool Eiszapfen might work because their handles are 36mm in the closed position, but there's no margin for error. The EK's @ 37.5mm is too wide.

Thanks

I also considered that one, but it would be too wide @ 38.2mm because I would have to mount it flat with the drain port pointed outwards unless I used a rotary. I know, picky, picky.

Thanks
