The siphon principle is clear, thanks. I guess I am not seeing the system correctly. Is the pipe coming out of the white ell into the pond blue?
Reason I am so interested is I just drove 7 hrs. to siphon down my pond which overflowed the dam and I want to construct one out of 6 inch and a 2 inch vent. Just not seeing the part that goes into the pond very clearly.
This is what I am going to build into my pond this summer and should be exactly what you are looking for.
