That is a really nice looking set up. Any ideas on what size pipe you would use for this? Is the pipe that goes in the pond and down the back of the dam buried under the surface or is it on top of the ground.
So if I am looking at this right, this is an overflow pipe and a siphon all built in one. Am I correct???
The way I understand it, and someone correct me if I'm wrong:
--Size of pipe is the same as what size is recommended for your pond's overflow pipe.
--It can act both as an overflow pipe and siphon, depends on how it is set up. Thats the true benefit of it.
--If you want it to act as a overflow pipe, the horizontal pipe is placed in the dam at the level you want the surface water to stay at. Then it still can be used as a siphon when needed.
