On what principal syphon works?

Answer 1

I will say gravity.

Answer 2

Syphon works on gravity and the concept of nature abhors a vacuum. If you know how to make a syphon, then you know that the exit end has to be lower than the input end of the tube.

Basically, the tube empties because of gravity. Since the tube would then be empty (and nature doesn't like that), something has to fill it back and that would be the liquid in the container. This will continue until the vacuum breaks, if air enters the tube the syphon stops.

Answer 3

I have some dirt in the bottom of my 5 x 6 x 2 pond. No bottom drain. I was thinking that I could possibly use a large aquarium syphon to pull that dirt off the pond bottom, through batting in a container with holes letting the pond water run back into the pond.


I figured this way, I won't have to add water if I filter the dirt out of the water (recycling).
