Why is it that the higher the inlet pipe is the more gallons you get to flow thru?
The company "dam piping" says they recommend the inlet 4' higher than the outlet, which is what Gus referred to originally. I can understand this concept because you can't siphon water to a higher area, and you want to make sure the siphon works at the point of inlet( that is if you ever want the water level to go down to that point), so the outlet has to be lower, even by a small amount. But to go higher than that recommended point (of 4') seems to be counterproductive to the amount of flow.

I would take both siphon inlets to the deepest points possible for two reasons...First, to remove the worst water in the pond every time there is a draining event and second, when going into siphon mode, 11,12,20 feet of head pressure will push water out far faster than 10 feet of head pressure and with 500+ acres of watershed, volume will matter!!!
