Implementing a Drain Valve

[sturadders]

So long story short i bought the PC 3 years ago, and have not change the liquid or done any maintenance in that time apart from a hoover. so yes it is proper dusty at the moment.

From what i figured out is that it is a EKWB Res x3 250 installed (WC-314-EK OCUK Code) With a EK-XTOP REVO D5 PWM - ACETAL (INCL. SLEEVED PUMP) WC-9ED-EK OCUK CODE. The outside diameter of the pipe is 15.91 so 16/10 compression fittings but not 100% sure.

So i either want to add a drain valve where the red mark is located on the image which will not be the best position as it is not lowest but would be easiest. or in the blue location add Quick disconnects or a T section with drain valve but no clue what is the best option or what parts i need.

I have done a lot of reading but not sure what part goes with what. Like the res and pump is G1/4.

Almost everything that is female Threaded for something to screw into will be g1/4
Almost everything that has male thread is also g1/4
I would put a T piece and ball valve on the inlet on top of the pump
Which happens to be the lowest point
Quick disconnects are great I love them
The main use for them I find anyway
Is to isolate the cpu and gpu for easier removal if needed
They can also serve as drain points
Currently doing that in my latest build

So would I need the following to do your process;

1 x EK-AF T-SPLITTER 3F G1/4 - BLACK ( OCUK WC-9J4-EK)
2 x EK-AF EXTENDER 6MM M-M G1/4 - BLACK ( OCUK WC-9J2-EK)
1 x EK-AF BALL VALVE (10MM) G1/4 - BLACK ( OCUK WC-901-EK)
1 x EK-STC CLASSIC 10/16 SOFT TUBING COMPRESSION FITTING - BLACK (OCUK WC-9SG-EK)
1 x EK-DURACLEAR TUBING 16/10 - CLEAR 3M (OCUK WC-9DC-EK)

Extender into the top of the pump 90 degree bracket, then a T Splitter with the existing tube into the pump connected there (pref shortened), The final part of the T splitter another Extender, with the ball valve installed and then the compression fitting with tube which I connect and disconnect to drain.

Seen as its been so long should I run any cleaner through and any recommended fluid I pref want UV Green

Yeah I'd do as above. If your drain isn't low down enough it's not going to be particularly helpful.

The way I did mine was to have a pipe come out my pump and go out underneath it. T-piece with one pipe running out the back side of the case to a tap for a drain. It meant that the drain was easily accessed, hidden and drained the whole loop.

BTW I'd say the fan in the rear of your case should be the other way around so it exhausts air, assuming that your radiator fans are intake.

I have dual radiators one at the top and one on front I will check fan config, it goes PUMP > GPU > RAD > CPU > RAD > RES > PUMP

If you don't have one also get a squeezy
Filling bottle with the tube on it
You can also use that to suck coolant out

Perfect yeah added a squeezy and a blank stop, Is there a formula on how much concentrate to add? I wonder how much liquid my system holds.

Thanks for all the help been researching for days and couldn't find a clear cut answer, even messaged OC and they said to post here so massive help.

You need to remove the mention of a competitor in your opening post.

Done

So its all installed thank you mcnumpty2323,

Now to try and get all the air out the system and and perform a leak test.

I can hear air in the rad I need to try get it all out what is the best way ? Tilting.

Ordered the parts last Sunday next day and they came yesterday, flushed the system and cleaned it all out what was a lot easier than expected.

Time for a good dust and new cable management of the workstation
