Bean Animal drains not draining properly

I think I can't get past 900 GPH because the air will not purge fast enough. My drains are about 3-4" under.

I only have about 1.25 inches from the top of the overflow box (about normal water level when all is balanced), until it flows out of the tank onto the floor. So not much time to fill the box, and purge. Maybe that is part of the problem.

Also, I read that when the drains are too deep in the sump, it takes longer to purge.

You are 6" under, and at 80% of full throttle, you must be flowing way more than 1000GPH. I know the system is supposed to be good to 2000GPH, but i can't get close to that.

So you drilled a hole in the elbow inside overflow box. You mean in the 90 elbow? Is it submerged when it's running? Because otherwise would't it suck in air and break the siphon?

Yes the elbow is submerged. I'm going to shorten the pipes though.

Thanks, I am now in the city untill Friday. I'll try a little hole in the siphon elbow when I get home.

I have a Hammerhead as well working at 80% wide open in the basement. My issue was with the main siphon. It wouldn't start up and my open channel would become my main siphon making loud gurgling noises. The problem was with air being trapped inside the elbow in the overflow box of the main siphon. Drilled a tiny hole at the highest point of the elbow. No more issues.

Once you shorten the depth of the pipe outlets, your going to be surprised at how fast it picks the siphon back up

The most likely reason that the air was staying trapped was because there wasn't enough velocity to pull the air pocket back into the pipe. When you shorten the outlets in the sump, that problem would go away. Try blocking off that little hole you drilled and see what happens after your fixes

Is it the horizontal runs? That would mean a whole redesign of the basement, moving the sump across the sump room 15 feet.

Bean has posted pretty specifically several times in his thread at RC that this system won't work with horizontal runs. He hasn't offered any thoughts on a solution for horizontal runs, he's just said if you've got horizontal runs, you're not using his system so he can't help.

Most of the problems people have written about are not with flooding, but with noise. The issue there is that the open channel stops being an open channel if it's not pretty much vertical. The theory of operation is that the water in the open channel clings to the sides of the pipe as it washes down to the sump, but sharp bends and/or horizontal runs wreck that effect.

I'm just about to test my own basement sump beananimal, and I've unavoidably got a couple of 22.5 degree bends in my open channel. I am hoping that it will work without issues...

I had read that.

I have managed to make my system go dead silent at the DT end. Not sure what it's like 1/2 way along.

I just want to make it flow a bit more than 900 GPH, and be able to restart without my assistance. Also, I think those horizontal sections makes the system take a lot longer to purge air, and to find it's equilibrium.

I'm sure yours will be fine with a couple 22.5 bends.

please forgive my ignorance but......whats the advantage of the Bean overflow over the Herbie?......Ive never used one, nor do I think Ive ever seen one being used on anybodies system that Ive seen.....seems like quite a lot of extra expense (two gate valves and three bulkheads versus one gate and two bulkheads) and fiddling around with the Bean......

Über quite. Absolutely no chance of flood tank. Lol well. Once it's running.

With the Bean Animal, the 2nd and 3rd valves are only there to completely isolate those lines during maintenance.
The advantage over a Herbie is thus;

The first line takes full flow as it's completely submerged.

The second, open channel line (with the air line) may take some overage from the first, but has air introduced into it, so it takes no time to handle the overage - there is no purging. When the overflow rises enough to block the end of the air line, the second now becomes full flow.

The third line is there as a last resort/backup.

[WindowMaker]

I like your judgement call on only using one valve for the BA. It doesn't make much sense to have one on every pipe when they are completely unnecessary.

[Daimyo68]

I think the 1 valve was mentioned somewhere in the second split of his thread. Luckily for me, I read that and saved some $$
