Water coolling question

[amarksman]

Hi everyone, I am building a wall mounted PC and got a little stumped here. Would greatly appreciate some help with this.

Here is the build so far: http://www.overclock.net/t/1608986/wall-mounted-pc-bumblebee

My question:

The reservoir is above the pump. The liquid will come from above and go to the right to the GPU. I'm looking to be able to drain to the left. Is there a problem with the placement of these two valves? For draining, I was thinking first opening the left, then closing the right. But then I was thinking about possible problems with the water cut off on the right not being able to flow to the exit. Any thoughts?

Thanks!

Best way to drain is usually with a T piece at the lowest point of the loop. Stick a valve on the end and open if/when you need.

My last custom loop had the same fluid for maybe 4 years, so it's not something you need to do often, but a proper drain hose and valve makes it so much easier.
