Honestly, I'm not sure myself. For my experiment, there was so much water, and the drain was so small (only 1 block wide), that I had to wonder if it would ever empty out. Sadly though, since the drain was made so small, the water was pretty much evaporating as soon as it entered into hell.

I believe that the reason why I was able to flood hell (somewhat) is because when I exited and reentered my world, the game was "settling the liquids" (as per standard world-loading routine). I believe that this might also work if the "settle liquids command" was used in a server world.
