If you can fill the pipe with water, the siphon will pull, unless there is an air leak. Can you push water fast enough to push out all the air?
Yeah thats what Ive always thought too but it's not true, water in a siphon can only be pulled up 30' no matter what, at sea level.
No matter how much water is down stream water can't lift more than 30' in a siphon environment
