Help needed for Bean Overflow

[mikebusc]

So I've been using the Bean Animal overflow similar to this one (Thanks BeanAnimal!). It works great except for when I have to shut my return pump off and then back on. When I do there's too much flow coming through the secondary pipe (the middle one) and I usually need to open the gate valve of the primary all the way untill it flows freely and then dial it back down till there's the normal trickle in the secondary. My idea is that maybe the heights of the standpipes need adjustment but I'm not sure how to correct it. Maybe the primary is too close to the bottom? It's just hard to get behind so I'd rather get some good info from this forum rather then trying to squeeze behind the tank with trial and error.
(And I know this may not be a "true" BeanAnimal from what I've read somewhere)

The primary need to be separated from the secondary

Yes I have them separated

I'm thinking its the pipe heights that matter but I'm not sure.

This sounds like it would be a potential problem if you lost power, and then it was restored, while you were away from your tank.

@BeanAnimal - Would you be able to help here please?

It's really not too much of a problem, just an annoyance. I mean I've lived with it all this time but now I'm ready to do something about it. When power comes back on it's just that most of the water goes down the secondary until I tweak it.

And just for clarification the primary drain opening is very close to the bottom of the overflow box.

Sounds like you need to raise the secondary stand pipe high enough that the primary can achieve full siphon before the water flows down the secondary... I assume the drains are very loud while this is happening?

It seems that diagram isn't an exact rendering of your set up.

1st thing to clarify, in the diagram the full siphon and open connect at the bottom. Is this how yours is set up?

with your issue, it sounds like you can't raise your open higher, and if thats the case, the only thing you can do is raise the pipe (full siphon) that terminates under the water (in the sump) so that the pressure required to get the full siphon is overcome and starts before it begins to drain out the open.

The lower that pipe is under water, the more pressure is required to get the water to flow.
