2 y/o bean animal now doesnít purge?

We have a bean animal system which we love and is super quiet. Lately (the last three months or so) the system doesnít purge for sometimes hours. So the ľĒ airline gurgles for hours. There have been zero changes to anything in our system. Our drain pipes are ľĒ below water and line previously stated we have never had a problem before. The system would purge in MAYBE 5 minutes and be quiet. Any ideas?

Have you tried opening and then closing the siphon stand pipe? Possibly it's not flowing correctly causing excessive water to flow down the open channel?

Iíll give that a shot right now. I have a feeling it wonít work but Iíve been known to be wrong before. From what I know opening and closing the valve raises do lowers the water level in the overflow, only, is that right?

Does it cycle, flushing the open channel (entering siphon) or does the emergency just handle the excess flow without the siphon starting?

That is not correct..
It regulates the amount of flow that the full siphon channel takes which effects how much goes down the open channel..
Sounds like you need to open the valve slightly to allow a bit more flow through the full siphon..
You may just have some buildup,etc... inside the pipes/stuck at the valve,etc.. and the flow can change over time as that happens..
Thats why bean added the caps to each pipe so that you can open them and basically give it a pipe cleaning as needed..

Its not uncommon for it to need a bit of adjustment every now and then..

It cycles. Drains fine. Just loud. Gurgles. Overflow fills up then drains fast. Fills up drains fast.

I did play win the valve and itís so much better though! I fed and so we stopped the return and then it took 20 or so minutes to purge. Better than all day long.

Good to know. I hadnít played with it in ages. Took a while to tune then it was set t and forget it.

Doing better now. Thanks for the feedback fellas.

No overflow is really "Set it and forget it".. Some are just more forgiving than others but in general a bit of adjustment may be needed from time to time with all of them..
Sounds like you got it sorted..

How is your open channel compared to the syphon height wise. A lot of times what happens is the open channel takes on to much water on startup causing it to not build up enough for the syphon to purge its air. I don’t know if it’s possible on your setup, but it would help if u can raise the open channel to where it is 1/2” to 1” above the syphon. By doing that it almost immediately purged the air to where the syphon gets going in less then a minute.

Unfortunately my tank is drilled and bulkheads are at the same heights. But now that Iíve re tuned it it takes maybe 3-4 minutes to purge and then itís dead silent. Iíll call that a win.

It sounds like your return pump has slowed down some & made the water level in the overflow box drop. It may be time for a cleaning. If I had to guess u actually had to close the valve a little bit to get it tuned, which means u have a little less flow then before
