Help with bean animal

[lacrosseboss18]

I’m having trouble with my bean animal. I have it plumbed and the gate valve open all the way. No water is going down the pipe with gate valve. It is all going down the second pipe and nothing down the emergency.
I have a hole drilled in the second pipe And nothing in the full siphon pipe.
the only other difference is that in the sump I have an additional 90 elbow to make the plumbing work. I’m thinking that is the problem but I should still be getting a little water down that pipe.
I’ve

attached a picture of the plumbing in the sump section.

Show us what plumbing you have on top side please.

we need a picture of the other side of your plumbing but if that's going on is your backup drain at the same height or lower than the main drain?

As the others have said, a picture of the top side of the drain in the overflow will be very helpful for more specific feedback. In the mean time here are a few thoughts that may be helpful - there are several minor variations of a bean animal, but the primary drain with the valve should be the lowest (whether it is a straight pipe of has two elbows at the top). Here is a link that may be useful:

The full siphon is lower.

The full siphon needs to be lower, needs to be fully submerged +, and full siphon and secondary should have small hole drilled on top.
Full siphon completely under water. Enough so that small hole on top is below water.
Secondary about halfway underwater at elbow

I agree the first thing is to drop the full siphon a bit and see what that brings

The primary is air-locked. Like others have said, lower the primary as low as you can. You could also just remove the fittings and put a strainer instead.

Air-locking usually happens because the exit to that pipe is too low below the waterline in the sump, so the water up above can't push out the air. The outlet to both the primary and secondary need to be ~1" below the sump water line. You need more water above the inlet than the outlet is deep below the water line.

gmacreef have a nice guide on how to do this. I stole their pic. Once you get water to flow, read their tuning guide. It takes some time to fine tune, and the smallest turn on the gate valve makes a difference if you leave it for 15-20 minutes to stabilize.

I actually use three open pipes of varying heights: 1", 3", & 5". It isn't totally silent, but it is nearly silent when there is a full siphon in the lowest pipe and a trickle in the second-highest pipe. Here's a diagram of what I had intended to make, except that the "U" for the secondary drain was too large to fit in my overflow:
