Drumz...this is really cool. I am having a pond built now, and settled for a traditional system instead of syphon, but I was really keen on the idea of syphon drawing from lower in the water column. I didn't know about this type of concept until now...problem solved! Thanks!

You state that it typically draws from much lower than 24"...how much? Should it be drawn from the deepest point possible?

Is there a reason to have the outer pipe 3" taller than the drain pipe, or could it be even taller?

Lastly, unless I can better understand what Leo is saying, how much for you to make another set of baffles and ship them to VA?
