Here is the video that I used to base my bell siphon off of, but I added a Harbor Freight air hose connector in the cap with a plastic airsoft pellet as a seal. As the water comes up the BB s pushed aside to allow air out, then once a siphon starts it pulls the ball into the fitting, sealing it. They work well, though not as fancy as this guys'.
