so is that screw looking part on top of this fitting actually a compression fitting?
Also, would my original drawing then be workable? i can leave just one qd fitting hanging on that drain line so its always acting like the plug, then when I want to drain I hook up the other qd end attached to a tube/bucket, and the water drains out?

Take a look at this page for info on how the QDC fittings can be used. It should give you a good idea on how you could fit a set of them into the loop you pictured:

Another option would be to use the following instead of the QDC fittings in your picture:

On a related note, to the idea of using the QD in the loop sans Tblock (basically, disconnect from loop, connect a qd female to now detached loop, and drain away); what kind of pressure drops are you looking at with using the QD versus just having the QD hang off to the side of a loop?

My thinking is that if you use the T block as a pass through, with a G1/4 screwed in QD on the perpendicular stretch (the middle of the Tblock)...you wouldn't see so much restriction as using the QDs as part of your loop. That's my plan now for when my overseas anthropological work is done at least.

Here is a link to some restriction testing on various quick disconnects (mostly Koolance versions) that may be helpful:
