Bean Animal drains not draining properly

[braid11]

I figure close to 16ft of head. But then I dialed the pump down with the 1.5" gate valve just above the pump. It's only open about 3/4 of a turn (It's 8 turns lock to lock). I need to calculate the flow.

I submerged the lines, and tried again. It will run with the way I have it dialed down. The height in the overflow box changes a lot, even after ten minutes. The saftey drain kicks in now and then.

It also makes more noise than I had hoped for.

I turned it all off, tefloned the caps, tightened the bulkheads some more.

I just think it needs way more flow. I will calculate the flow next, based on how fast it fills a volume of water in the DT.
