I've been trying to get a siphon working in a 30m 3/4 hose. Drop is about 1m with the first 10m being pretty much flat, so I need to move quite a large quantity of water to get it started . I did get it working once with a jiggle/ball siphon valve but it's a lot of work and I haven't been able to make it work since.
Considering making my own from some kind of plunger with 2 check valves. Does something exist off the shelf that will have a high throughput and for 3/4" hose, or does anyone have any tips on what construction would look like?
