There are videos and advice all over the Internet in regards to the best way to drain a liquid cooling system. In my opinion not one of these I’ve seen offers a safe and easy method to drain your liquid cooled computer. Last week I was needing to drain the fluid from my new liquid cooling setup. A few weeks before I had started to look at my options in regards to completing this task. Some systems have a drain setup. Mine isn’t one of those. In the end I came across a $45 solution that is quick and easy.
So what did I buy to drain my Thermaltake ProWater 850i Liquid Cooling system? I purchased an Ace Hand Pump Kit to drain this computer. Any hardware, home improvement or well known retail outlet should have something similar. I think the unit I bought is a little overpriced. The reviews stating that the cranking motion feels forced are correct. But in terms of saving aggravation and time this device did what I needed it to do. I’m still not sure how effective it would be when used to drain oil. I would think it would do gasoline and other liquids like the packaging claims. What I can tell you from my experience is that it had no problem sucking the PrimoChill PC ICE Non-Conductive Water Cooling Fluid out of the Thermaltake ProWater 850i. Why anyone would try and drain a liquid cooling system in any other way is beyond me.
When using the hand pump you reduce the risk of fluid reaching the components installed within your computer. Granted some fluid will be retained inside of the radiator, pump and waterblock. But this amount of liquid is very minor. You can place a towel under the connector you are taking off for safety. Then use a cap over the waterblock connection. To reduce any chance of leaking even further you could have your computer case laying flat. Of course this would be after you have removed the reservoir and pump.
With the Ace Hand Pump Kit you should avoid reading the setup directions. They make an easy process complicated for some reason. The diagrams to me made no type of sense in regards to putting the product together. Once you have the hand pump assembled it’s very easy to drain your liquid cooling system. Just place one end of the hand pump tubing into your liquid cooling reservoir and start cranking. The liquid starts to flow out almost immediately. Of course you should be sure to have the other end of the tubing inside of something to capture the fluid coming out of your system. But all in all it is a fairly easy and painless process.
If you had the money purchasing an all in one system such as the Zalman Reserator XT Water Cooling System would reduce the likelihood of any liquid leaking onto any of your hardware. But the Zalman isn’t as low priced as the Thermaltake ProWater 850i Liquid Cooling system.
