Questions about Draining/Flushing/Filling my loop

[Cmptr]

So I just have a few questions about my loop.  I do apologize if I should have created multiple topics.

 

Will blowing through a tube connected to the loop while the pump is empty, but the loop not totally empty; will that damage the pump?

 

For my next questions, I have an image and an illustration.  

 

 

 

The red is the drain valve.  

Top and bottom are 360mm rads

Far right is a 240mm rad.

The inlets and outlets that I have marked are in the same position as the loop itself, including the locations and orientation of the rads as well.  Only difference here is the pump/res combo is connected to the 240mm rad.  

 

When draining the loop through the drain valve using steps:

1. Open drain valve
2. Open fill port on top of res
3. Let liquid drop out.
4. Close drain valve
5. Fill up res
6. Run pump (Obviously turning it off before getting dry)
7. Turning off pump
8. Repeat steps (Keeping fill port open)

With how terrible my loop is set up, will all the old fluid get flushed out?  Or is this going to be a nightmare?

Instead of blowing I'd just carefully tilt and flip the case to get as much fluid out as you can.

It's basically like you said, open the port, drain it, tilt and flip the case around (carefully of course) to drain as much as you can and fill it back up. Rinse and repeat as much as you like. That should be enough for a simple fluid refersh. For a really deep clean I would still take it apart to e.g. clean the blocks with a toothbrush.

See..  I kinda already blew in it, and my OCD is driving me nuts thinking that I damaged the pump.

Do I have to contort the PC?  Or will all the old liquid eventually natural come out the drain port?

Pump is probably fine. Yes, you'll have to turn it around and about to guide all of the water out. As there will be places where it can get stuck. Your bottom radiator, for example, if I'm seeing correctly won't drain if you keep your PC upright as the drain port is above it.

Won't the pump suck some of the liquid that is in the bottom rad when I turn it on?

If you just open the drain port your not taking out the old stuff since it's below the drain valve and physics works against you in that configuration. The pump will suck from the reservoir and other inlets, so new stuff will flow through it and dilute the old stuff, but it is still a radiator's worth of fluid in there. If your goal is flushing it then it's more efficient if you can get as much out as you can before adding fresh fluid.

Pump is not only "probably fine", it's absolutely fine. Blowing into your loop is absolutely not a problem and many of us use a data vac to help drain the loop when using hardline. You're fine.
