Suck on the drain cock?
Alternatively,
1) Don't 2) Powerflush 3) Cut in and add a drain valve
I wonder if you could blow into a drain valve on a rad or something and force the water out?
Tried that yesterday/saturday using a track pump and a scrader valve from a sacrificed tube. Didn't work.
Think you were right with don't.
