water equalize to the same level (^^^) just above the pipe (==)?


Yes. Thanks for the pic!

yes but it still wont flow uphill as fast as your pump so as soon as
the pipe in the vf gets near the top of the water you lose siphon

If it can't be fixed with bailing wire or duct tape
its not worth fixing

2 is my reservoir pond. 1 is my VF. The pond (2) has a bottom drain that

It looks like it should, assuming (3) is open with no pumps, no
valves, etc.

My veggie filter (1) is actually above the koi pond (2) and I use 2
Oase 3700 GPH submersible fish basin pumps to move the water. While
you aren't really supposed to pump the bottom uphill, it is working
reasonably well for me. I've got a tanin problem and a bit of an
algae bloom because I don't have enough plants yet, but it is working
reasonably well.

OK Jeff,

This is what I think? You are playing with complex laws of physics. I try
to work with the more simple aspects of gravity!
Pump up, gravity flow down! What goes up must come down.

So I will either elevate my VF, pump up into it, and let the water flow back
into my pond

or
I will have my veggie filter lower than the output portion of my pond. Of
course the output portion has to be much lower than the top of the water
level in my pond. Say your VF is 12" lower than your pond, then the output
portion of your bottom drain from your pond can be 6" lower than the water
level in the pond. Then simply pump the water back into the pond from the
VF. No siphon to deal with, no head to calculate, and no major backflow to
deal with.

The lowest your main pond can go down is to the level of your bottom drain
out put or 6" low. And your veggie filter can never back flow back into
your main pond.

My 2 cents.
