Incorporating easy draining features: what would you recommend personally?

post #1 of 17
Thread Starter 
Hi all,

Below is my proposed loop. Be sure to note that my pump is not part of the bay res but rather part of the CPU block. Given my layout and situation, what would you advise me to do for draining purposes? I'd been looking at quick disconnects as a way of making draining easier, but a forum search suggests this might not be the best option as far as cost and restriction goes.

How would you go about it personally?

A T line with a valve somewhere... like near the rear port of the 120mm rad. It will drain a part of the loop, more if you flip the rad.

I would put a set of quick disconnects on the 120mm radiator, one threaded onto the rad and the other connected to the tube from the GPU. Then have an additional set with about a foot of tubing on each. When you want to drain disconnect the set in the loop and connect the spare set. Then blow into one end and water with flow out the other

1. Flip 120 downwards, attach a T-Block + Ball Valve to one of the ports,
2. When ready to drain, attach tubing to end of ball valve
3. Open top port ( If res is top port, open that fill point *ONLY IF ITS THE HIGHEST, other wise water from the radiator will rush out the fill port)
4. Turn the Ball valve to open
5. Watch gravity drain your loop biggrin.gif no blowing, sucking, licking or anything biggrin.gif

and if you're lucky and your loop is in a great position, you wont even have to tip the thing to get some out tongue.gif

Here's a pic to help demo.



And these are the items you'll need.

This is the T Block, don't mind the barbs on the picture, just add double G1/4 Connectors on each side

This is the Ball Valve

Ahh all awesome suggestions, +reps given! smile.gif

I think I'll run with that T-fitting + valve idea, since it's probably the cleanest and least restrictive option for me to work with. Just to confirm, down in the red area circled below I'll attach a Male to Male adapter to the outlet of my 120mm rad, then connect a T-Block to it, then another Male to Male adapter on the outlet end of the T-block, then a regular old compression fitting with my tubing attached to that. And on the 3rd, middle port on the T-block, i'll thread another Male to Male adapter onto it, followed by a tap valve?

Is that tap valve I've linked above what I think it is? I've assumed it works just like a regular household tap in the sense that turning it one way will result in no flow, and turning it the other way will open it up to allow water to flow out of it (providing I unscrew the reservoir fill port)?

Yup I'll show you how mine looks, but instead of attaching it to the rad I attached it mid line, and drilled a fill port and drain port since I didn't have the highest part of my loop the res

Ahh yep, too easy!

Hmmmm might have to drill a full port too.. My bay res will be slightly lower in altitude compared to the 240mm rad... Physics and fluid dynamics weren't exactly strong points for me at school, but can I get away with simply attaching some tubing to my bay res fill port and holding it up above the height of the 240 rad? Would certainly prefer to not have to source some power tools to cut a fill hole if possible haha

Yeah, you'll need a 3/8 to 1/4 adapter or fill port drain port plug, when I had a Bay res I used this and left a 1/4 plug on it when not in use, but I had decent room space above my drive Bay to slide it in because the g1/4 plug will be sticking out a little
(this is assuming your res has a g3/8 fill port)

I usually use bitspower fittings, actually always.

But recently I've tried the koolance qd3 quick disconnects, they are alot less bulky and are easy to disconnect. If you wanted to go that route you can do that aswell

One of these guys works pretty nicely for an inline drain;
