How do I drain my water cooling loop?

Help!
Normally I'm the one giving advice around here, but my knowledge of water cooling is limited. I built this loop and thought it'd be easy to drain it, so I didn't put any thought into it at the time :D. Can this loop be drained easily??? I've put a lot of thought into it and couldn't think of any simple way to do it (actually couldn't think of anyway to do it). Some experienced help would be very much appreciated and I'd like to throw my GPU into the loop soon.
Thanks!

    When building your loop, you have to prepare it for draining too. I mean, you don't just build the loop, you add to it extensions that will let you drain it as needed, for when you'll need to service the computer. If you didn't allow for this, that's a problem, because now it's too late :) I have a double loop (for CPU and GPU) with hard tubing, like you, and both loops are extended at the bottom of the case to allow draining (at the lowest point in each loop there's a T connector, two of the ends of the T close the loop, the third end goes to a draining tube (flexible tubing in my case) that ends up in a drain valve (https://www.ekwb.com/shop/fittings/extra/ball-valves)) When i want to change anything, i open this valve over a bucket, let all the water out, and can start servicing.

    Here are some pics of my setup, notice the flexible draining tubes at the bottom of the loop: https://imgur.com/a/gtpb0

    Ok, so you didn't know about this and now you have a loop that is not prepared for draining, what can you do? Unplug, of course; and then you will have to release one of the tubes. Seeing the picture of your PC, i recommend loosening the rightmost tube, that goes from the reservoir to the radiator. Ideally it should be the lowest one, so that gravity helps you draining, but in this case i would try to spill as little water over the electronics as possible. Remove all electronics you can from below that tube, take a few pieces of fabric and a bowl, remove the tube as carefully and quicly as you can, and try to put the bowl under the stream, and use the clothes to block all other spills. It will be a mess, but if you're careful, quick and lucky, you will make no permanent damage. When rebuilding the loop, make a draining system into the loop (with the valve at the bottom).

    Good luck with it! :)

  2. As mentioned above, you want a drain port in your loop with ball valve. since you don't have it right now, the only practical ways to drain your loop would be:
    1. to take it to a bath (or any other place where you can spill liquids) turn the case on the side (components up) and open the loop (disconnect the tube from pump/res to radiator on both ends for example).
    2. take a large syringe and start sucking the liquid from the res. close the loop, tilt it to get liquid from rad to the loop and repeat.

    Now that's far more clever than my "be-quick-and-hope-for-the-best" solution xD

  4. Most reservoirs use G1/4 threaded ports for filling, also. You could apply a fitting and flexible tubing to use this as a drain as you tip it.

  5. ^ the loop has to be open in additional spot for liquid to exit. don't think he have enough ports for two tubes.

  7. Right, he still needs a vent in order to drain.
