Drain port

Image below is an approximation of my system layout. Trying to figure out where a drain port can be installed but cant for the life of me see how such a thing can work as inteded with the components laid out like this.

If a drain is installed at the bottom of the reservoir only that top rad and the reservoir will empty.

If a drain is installed just before the inlet/outlet at bottom rad, I assume the GPU/CPU blocks and top rad might empty after a long while and the reservoir as well as bottom radiator will retain all fluid as I understand it. I assume the pump top will prevent gravity from emptying the reservoir/top rad path.

It's impossible to place a drain such that all of the coolant will come out. No matter how much you think it through, there will always be some trapped in a radiator or block. Place it somewhere that will get most of it and allow you to get all of the coolant from the sensitive components. Like below the graphics card. Then you can get them out safe and dry and just tilt the case to get the rest.

Coolant can behave very strangely in a loop, especially when air starts to get trapped as you drain it. But if your observant and careful you should be able to drain it/disassemble without much aggravation.

These days I use quick disconnects and just remove and drain what ever part I want to replace or work on.

It is also easy to drain parts by attacking a couple of tubes with quick disconnects at one end and open at the other end.

I had to work on a set of GPUs today and emptying them and refilling and refitting them afterwards took just a few minutes.

What ^he said. For me, the primary purpose of a drain port is to get most of the fluid out, so that when I start disconnecting components I don't get a deluge of coolant, but just a bit of fluid which I can wipe off with a few paper towels.

Also, I wouldn't expect the pump top to hinder the draining too much TBH, it's not like it's made from magic fluid flow resistance stuff.

Good to see you back!!

But I'll basically say what the other guys said, a drain port is just go get most of the coolant out. The rest should come out when you clean them youtself

He, I see you've made a few posts in my absence.

Feels good to be back, I probably won't be posting quite as much as you seem to be having to, but I should be able to hang around regularly-ish again.

(sorry for off-topic response, but it felt a bit impolite not to)
