I have a set up just like mm67's. Works great, leaks only 1 or 2 drops at the most and I don't have to worry about all the extra tube potentially blocking air flow. When I am ready to drain I just use the male end that has extra tube connected and down into a bucket and click it into the female I have on the back of my res, open my stop filling on the top of my res and gravity drains 90% of my loop. I do have to rock my case a bit to get water out of the corners of the top rad but it keeps it all from dumping on any of my components.
Then I use a spare barb fitting with extra tube and a funnel to screw into the top of my res to refill. Love my EK advanced, so many options!
