Two Questions - Mini-valve drain and testing the water system custom cooler - Doubt
Hello everyone,
I have two questions and I want to understand how it functions.
Question 1: The mini-valve designed to drain fluid from my cooling system. Could you explain its operation or provide a video link?
Question 2: Based on the first image, how should I connect the button to test the loop for leaks? I’m unsure about where to plug in the Molex and running the pump with the button on or off. It would be helpful to know if it’s easier to check the fluid flow in the system.
I have two loops:
Loop 1: reservoir bottom - rad - block Rams - CPU - MOSFET - block Rams - reservoir top
Loop 2: reservoir bottom - rad - GPUs - reservoir top
Thanks!
The molex adapter for turning on/off should simply link to your pump. But if you have a single molex, you'd need a molex splitter since you'll be running two pumps at the same time.
When draining, you'll mostly rely on gravity and pressure when opening the valves. If you're not at the lowest point, you might have to get inventive to drain the lower chamber. For my approach, I'm using two mini-valves. I close one to stop coolant from going through the loop, and open the other to drain.
Nice setup, by the way.

Thanks for your feedback and your kind words about the effort in my project.
I can perform a leak test separately; I plan to use distilled water first, creating loop 1 and then loop 2. Would that work?
The challenge of draining the bottom of the drain is not just creativity but also strength, especially with the Corsair 900D case being quite heavy. Thanks!!
I understand what you're referring to about the extensive effort. It pays off in the end.
You can verify each loop separately—no issue there, just ensuring proper flow and checking for leaks.
That was a case a few years ago with an 800D before my current setup; it was massive and heavy. Your 900D is even more significant.
For removing the loop, I used mini valves, connected a length of tubing and quick disconnects, and relied on my strength to push coolant out manually using valves. It wasn’t too tough.
Also, it would be great to see some photos of your finished system when it’s complete—always appreciated for new custom builds.

How did that work for you? I had a similar setup a few years ago with an 800D before my current one; it was much larger and heavier. Your 900D is even bigger, lol. For draining the loop, I used mini valves in combination with a length of tubing and quick disconnects. I physically pushed out the remaining coolant using my strength and force, without relying on the valves themselves. Not too hard after all. Also, it would be great to see some photos of your system once it's complete—always nice to see pictures of new custom builds. Sure, I'll share more pictures about the project. Thanks again!
Apologies for the delayed response. Generally, yes, that's the usual method. I actually have one in my system, which I close initially before opening another to drain.
Sorry for the delayed response. To address your question, generally yes, that's the usual method. I actually have one installed inside myself; I close it first, then open another to drain.
No issue there, by the way—what do you mean by these connections H_AMP_FAN and W_PUMP on my motherboard?
Can I connect my 140mm fan to H_AMP_FAN? The door is right next to this fan. All other fans are connected via Molex fans and splitter terminals.
I'm really embarrassed to mention putting distilled water in the system. Lol
They follow their claims through labeling. The w_pump acts as a PWM header if your pump is compatible, but you seem to have D5 pumps. Regardless, the pumps would still require Molex or SATA power. Using the header just gives more control over pump speed depending on temperature.

The h_ amp indicates that the header supports a stronger fan with higher amperage. Most motherboard headers are rated for 1A maximum, which might allow higher currents safely, though most fans operate at lower levels.
Unfortunately, I added water to the system during the leak test, causing leaks in the two reservoirs between the pump and the mod top. This nearly damaged the system; I suspect the installation of pumps, the mod top, and reservoirs was incorrect. I'll include this in the pictures—I'm really concerned now. I took everything apart and dried the water away. What could be going wrong?
I'm worried about installing the wrong kit (pump, modtop, reservoir). The photos show the leak locations. Is there something wrong with what's left over?
In the video below, I documented my issue:

Noticing issues with the video link. The problem seems to originate from the area around the O-ring reservoir base where it connects. Regarding the components, what models or makes are available for the pump tops, pump accessories, and reservoirs?
