Why does my loop drain suck?

[DSteiny18]

I thought I was being smart when I put in a valve to my water loop so i could "easily" drain it. Well i just tried it for the first time yesterday and my experience was less than "easy." It seems like there's a huge air bubble in my loop causing only like 30-40% of it to drain without my shaking/rotating the entire PC....my gpu blocks come in tomorrow so if there's something I can mod before finishing up with the graphics cards that'd be awesome. Oh by the way I think its in one of the front mounted radiators but I cant be too sure. I attached some pics of my loop...  sorry that some are sideways they arent on my pc?

Easiest solution (from someone without any custom loop knowledge. Please dont kill me) without any form of debugging will be to buy new coolant, and rebuild the loop and test all the parts to see if it was a part issue or a setup problem.

If you're going to use a T fitting to have a drain tube, you need to make sure that it is placed in the lowest possible point in the loop. If you really want it to work well, then you also need to get a bleed port at the highest point of the loop. That way you would open the drain tube port, then you open the bleed port at the top of the loop. This would allow the water to drain out the bottom port without the air entering the system having to fight against the flow of water to move up into the loop.

It's the same principle as shotgunning a can of beer.

so when I drain my loop I take the top cap off of my res, but I guess technically I could get a little higher up with the res thats mounted on the top of my case (in the psu section) and the t fitting is in the lowest part of my case, but there are also the input/output of the 2 front res's on that same height..... its the only way they fit in the case

In order to help you out I would need a better look at how exactly you have your loop set up. The pictures you posted are at weird angles, so it's kinda hard to get a good look at what is the top of the case. and the bottom. If you are wanting to redo your loop to work better, comment/tag me, or PM me, a list of the WC components you are using and what case you're using along with straight up/down pictures of the system and I can give you some recommendations for any changes that might help.

I'll get some better pics up immediately, thanks!

you don't have to remove the res top, open it enough to allow air to gain entry

of the system while draining.
