As with all fluids it’s essential to properly prep your system for the fluid you choose. Be sure to check and follow the correct prep guide for your fluid.


We typically suggest going from a top port input that’s open your reservoir. This will ensure the pump never runs dry and will also allow easy access to get fluid in your system. There’s a few tools that can help you with filling your loop. One of our fill bottles is an easy and cheap way to get the fluid into your reservoir without spill. You can also purchase a threaded funnel to create an even easier filling process. 


With the Pc turned off and cables disconnected, plug in the jump start cable to your PSU, and the molex cable to your pump. With everything ready to go, fill your reservoir up with your fluid. Then simply cycle your PSU on and off without letting the reservoir empty with fluid. Thoroughly check your system for leaks and if everything looks good, repeat the process. Fill the reservoir, cycle the pump. Once your system is full, you can keep the pump on to rotate the fluid through. 

If you don’t have a Jump start cable, here are some other ways that you can get power to your pump.

  1. Vario Pumps that have physical manual speed controllers.

  2. Physically shorting out the pump. Look at diagram on doing so.

  3. There are several products on the market that allow for you to plug your pump in and control voltages/speeds. These are an extra cost but worth the purchase if you’re constantly filling and draining your system.  

  4. Leak testing your loop first, then going into your bios and setting your PWM pump to its lowest speed. It’s important that you leak test your loop prior as you’ll be filling the pc up while it’s plugged in and running. No fluid can get on any components during this process. Extra precaution needs to be taken as this method is more dangerous. We advise only doing this if it’s your one only option and that you understand the risks. 


After your build is full with fluid, let the pump run allowing air to release. You can keep the top port open as it will help with releasing air. Keep a close eye for no leaks through this process. You can also slightly tilt your PC back and forth and side to side. Just be sure to watch the open port on the of your reservoir.


After you feel that most air is out of your system, you can disconnect the jumper, plug your pc in and get ready to start your computer up for the first time. We recommend doing one last check around your components to make sure no fluid spilled during the fill process. Once you know everything is dry, take your paper towels away from the pc and screw your port cap onto the top of your reservoir. We strongly recommend buying a Pressure Release Valve as it ensures that no pressure builds up in your system.


Plug in your PC and turn on the computer. Do another close check on your loop. For the next few weeks check your loop and monitor it closely. You can also go into your bios and find your desired speed for your pump. The D5 pumps are incredibly powerful pumps and don’t need to be ran at full power. With Base fluid, running pumps at high speed won't hurt your fluid. 


As recommended above, we strongly suggest building a drain system in your build with a proper drain valve. We can find a variety of those valves on 


As with filling your loop, draining precautions should be taken in the same way. Unplug PSU completely. Add paper towels around your hardware. If you have a drain, you can get a fitting with some flex tubing and connect it to your drain. In addition you can get a bucket and put the tubing straight into that bucket.


Once your ready, open your drain system. At first water will be coming out slow, but you can undo a port cap/pressure release valve and release more air to allow water to drain quickly. Depending on your loop set up this should get most of the water out of your loop. You can shake and move your pc around to try and get water out in hard to reach areas. 


Depending on why you’re needing to drain your system, this step will vary. If you’re simply draining it and adding new of the same fluid, you can simply close your drain valve, fill your system up with some Di/Distilled water, run it for a minute with your jumper cable, then drain. Cycle this a few times, then add your new fluid. If you’re deciding to run new show/opaque fluid, then checkout our prep guide on properly changing over. This will require taking apart your system, cleaning components, and properly prepping your system.

You may be needing to simply change a component as well. We recommend getting a small container/bowl, and then safely disconnecting fitting that will help get the rest of your fluid out. Be aware that fluid will still remain in your radiators and blocks, so you want to be cautious while removing these. 

NOTE | If any water spills on your system while its off, we recommend you getting a dry blower and setting it to a low heat setting. Get the water dry without warming the hardware up too much. Then let that hardware sit for as long as possible before plugging it back in. 


  • You don’t need a drain system but it will make your watercooling life incredibly easier. If you don’t have it rest assured. You simply follow the same process, but it can be a little messier. You simply disconnect a fitting on your reservoir or a fitting far away from electronics, and have a bucket/container under the fitting. If done correctly the water will rush out into the container. Just be aware of your hardware and never do this when the computer is plugged in. 

  • All of our fluids and preps are non toxic. You can dispose of them in any drain. 

  • If possible don’t feed your pump outlet straight into a radiator. Radiators hold significant air, and this setup will create more difficulty when filling your loop up. If for some reason you can’t get around this, we recommend not using Vue as air induction is a factor of failure for Vue. You also may have to shake and rotate your PC case while filling to free the air in your loop if your pump is feeding into your radiator. 

  • If you use any show fluid and see any type of residue or drop in fluid then immediately drain. it’s best to take your loop apart and soak and rinse your hardware. The residue should come off with ease if you’ve drained immediately.
