Bean Animal overflow problems. Help

[Dondante]

Is what you are hearing the sound of the water splashing through the bulkheads into the box? That's what I experienced when I had that issue. Back to my picture, notice the level of the water compared to the bulkheads. The water level is over the bulkheads, this eliminated that sound for me even if it was a little cringe worthy to have that water that close to the top of the box.

Ok. Yes. Maybe it isn't the weir. Seems to be the bulkheads into the box.

Should I raise the secondary some more?

Yes, raise the secondary some more and let the water level be about even with the back of the bulkheads. This is the real reason why in mine there is only a slight difference between the secondary and the drain. I would see little harm in the top of the U being equal to the emergency. The reason for that is that by that point you already have a problem you need to address.

If this is a true Bean Animal then I would recommend following his design. It is probably the only fail safe system out there that is 100% quiet when set up properly. As he is so fond of saying, and rightly so, any deviation from the design then it isn't a Bean Animal anymore - thus suggesting the elbow use on the primary if you removed it.

I also could have misunderstood if it is still there.

That was the ticket! It is much quieter now. Still some noise from the weir but the noise coming from the bulkhead is almost completely silent. Thanks, man.

Is there a better diagram showing water level etc? Where that airline is going etc? I take it that middle is the primary.

I'll play with the valve to see of I can raise the level a bit? Not sure that will work. Right now the drain is not slurping etc. It's pretty dang stable

Not that I'm aware of - probably a generic search on bean animal using google may provide an image. I was trying to take a picture of mine but I'm afraid it isn't coming out. My tank is setup quasi peninsula style and the overflow is a bit close to the wall I wish I moved it more in the middle but the joy of hindsight being 20/20 right?

Hopefully the mods don't mind - but here is the URL of his which you may already have:

I will say that I had a similar issue with more water down the secondary than primary and my issue was because my primary and secondary being the same height. From bottom of over flow, to elbow, etc. Once I shortened the secondary everything seemed to be OK. However, I will still get some water flow down the secondary which normally wouldn't be a bad thing but my secondary is after the skimmer pump intake and closer to the bubble trap. So when water goes down the secondary it more than likely isn't being picked up by the skimmer.

It's pretty dang quiet now.

One thing I discovered. The weir cover wasnt snapped on all of the way. There was like a 16th inch gap on one side. I snapped it on all the way and that made a huge difference in the noise. Just a tip for future readers of this thread.
