Flush of water with a Bean Animal?

[Zero_Cool]

Tried to plumb a Bean Animal drain. Must have done something wrong.

Periodically a large flush of water drains which causes the level in the sump to rise and then the high water alarm goes off.

It's an internal overflow. Main siphon sits at 12", secondary durso at 22", emergency at 22.5". Durso has an airline.

Is this too much flow?

I raised the water level in the overflow using the gate valve on the main siphon drain to try and quiet the waterfall noise. Could I have raised it too much and have too much water resulting in a secondary siphon being periodically created in the secondary drain?

Flushing of the open channel is because you are running too much through it and as you note a secondary siphon is periodically created. You Just need to adjust the gate valve on the primary so that the secondary just takes a small amount of water. Emergency is awfully small. I’d upside the pipe above the 1” bulkhead.

Thank you.

So open the gate some to prevent the flushing. This will drop the water level in the overflow and lead to the waterfall, correct?

Do I just need to then raise the height of the secondary?

As for the emergency, won't the max flow rate be limited by the 1" bulkhead?
