Ever used an external pump for draining the loop?

I need to change my water in a few months and I was wondering if anyone ever used a submersible pump to help suck all the water out of the system? It would seem to be a better way than rocking the case back and forth for ten minutes.

I have a drain tube and a T-Valve at the lowest point in my loop. I was thinking of using one of those submersible fish pumps, attach it to my drain tube, open the valve and open the cap on the res. I would also pour new distilled water in the res as it drains to help clean everything out.

Would this work?

what i was thinking of doing when it came time to flush mine was pop one of the tubes from the rad, put the submersible pump on that. Drop the pump in a 5 gallon bucket of distilled water, maybe with some sort of cleaner, and let it rip. Hook up a length of tube to the uncapped res and let it drain out the door. I think it would be a good way to get a good flush.
 
Yeah, I picked up one of those little 120v fountain pumps and spliced it onto a Tline at the bottom of my loop. Honestly, it wasn't needed, as gravity did all the work. So I took it out later.
