haha ahh thanks very much
The only time mine ever drops below the intake is when I do a water change and then I just shut off the valve below my tank before doing that and as soon as the water gets back above it I open it back up and siphon is never lost If I experience a power outage my sump actually fills and does the same thing as if I shut that valve off and since the water actually never drops below the intake it never loses siphon and when the power comes back on voila I have overflow againSorry to bump up an old topic.
I can't understand how the siphon is maintained when water drains below the intake. I thought to maintain the reserve has to be inline with the tank water while still carry water over the highest point. I imagine maybe the valve keeps air out enough to maintain water over the bend? What happens if you accidently knock the tube?
Would you elaborate a bit on the physics behind the intake siphon and maintenance please?
