Either your setupis like Turbokeu's and there's no confusion.
Or you have 2 T's at the top, connected to two hoses (after 2 taps).
Hose 1 - Intake: this hose must finish *over* your system (over everything, including rads, T's and other tubing)
Hose 2 - Output: this hose must finish *under* your system.
This creates a 'syphon' (i dont know the exact english word). Water will always get drained towards the output hose as long as it *ends up* under your system... Try it - it's magic.
