Implementing a Drain Valve

sturadders · 18 Apr 2020 at 23:52

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

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.

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

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

Yep sounds right
And 1 blank/stop I always shove one on the ball valve as an extra precaution
Then just remove it when want to drain
Ball valve is unlikely to leak
But I have accidentally bumped one to the open position before while working in the pc
So that blank/stop was extremely useful

If you drain it and the tubing looks manky
Probably easier just to put new tubing in as it's cheap anyway rather than try
To clean it out
Usually I use distilled water and add mayhems concentrate to it
And can't believe they built that but no drain valve
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.

Usually it tells you like 1 small bottle makes a litre for example
You can buy it premixed though if you want to in litre bottles
Probably want 2 litres to be on the safe side, always better to have some extra than not enough
Obviously you could wait and measure how much you drain out of it if you want to
And happy to try and 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

Mcnumpty2323 · 27 Apr 2020 at 15:09

Good job
Take a bit out of the reservoir
Leave couple inches from the top
That's where the air will end up
Very slowly open a port on top of the
Reservoir you will hear air escape
Tilt the case, give it a shake, run pump at high rpm
Every now and then slowly open the port on reservoir until you aren't hearing air
Escape
Give it day or 2 and slowly open port on reservoir again

Usually it will work it’s way out with cycles of the system but to get it out easily you can just run the pump on maximum speed and as long as the loop is sealed, all plugs in place etc you can tilt the case as far as you can go. Just be sure to power down the system after and open a plug in the reservoir to let the air back out.

Definitely looks much better with green coolant also :cool:

.

You can also easily smarten the route up also. Buy a multiport top for the res and an acrylic threaded insert.

Put the front radiator one fan slot higher or upside down to where it is now so ports are on the bottom (or 360mm? :cool:

).

Out of pump into bottom rad->behind mobo tray into top rad->gpu->cpu->top of res via multi port top.
