Long story short, a year or so ago I bought a custom 3xs watercooled machine from Scan UK.

Now I’m wanting to upgrade the GPU and water block but just realised my custom loop doesn’t have a drainage valve.

Wondering how I can go about draining it?

I saw one video where the guy got a syringe and emptied the reservoir which I could do but then after that how would I get the rest out of the tubing?

Thanks

I say this as a relatively new watercooler on the scene. But my PC has a drain valve, I just can't get all the water out through that port alone. I have to take it apart at the GPU and try not to spill while I dump it all out there. Then there is always coolant stuck in the rads no matter what.

My ultimate question is... how can I drain it without having to take some of it apart?

I'm able to drain the res fairly easily, its just the rest that gets stuck in tubes that I can't figure out.

So I made a really big mess here. So I didn't purchase a valve when I built my PC and now I wanna drain it to change the fluid. Sadly I don't know how to do it. Whatever fitting I open and try to drain by running the pump, then after that the pump runs out of water (my reservoir is empty) and I get to 0 again. Maybe you could help out please.

I built my first custom PC back in March of 2015. It has a custom water loop for cooling, but in my eagerness I forgot to add a drain into the loop.

• Reservoir > Pump > 480mm Radiator > GPU > 480mm Radiator > CPU

• Max Temp at full load 125* F

I will be upgrading my system when Nvidia releases the 1080TI which means I'll have to open the loop up. If i go through with the update I'll move from a single Titan Black to 2x1080 Ti, and I'm contemplating splitting the CPU cooling into its' own loop and the GPU's into their own loop

• How to drain the loop without spilling water everywhere?

• Where should the drain be placed in the loop?

• Is splitting the loop worth it?
