Eclipse L Overflow plumbing

[kkenevan]

I'm havaing a heck of a time silencing and maintaining the level in my over flow. The way I have it set up is the center is my drain with a gate valve. Left is main drain and right is emergency. The way you see it know is pretty quiet but I can't get it to stay lower and not make splashing noise when its lower than the emergency drain. Can someone post some pics of thiers maybe or some better explaination. Tha is alot.

Do you have gate valves on both the primary and secondary?

No.

Generally you want a gate valve on the primary, some put one on the secondary but it's not necessary, and the emergency is un-valved. If the primary is not gated it may be the issue. Check out this write up on setting up a bean animal overflow, courtesy of Marine Depot. Its helped me in setting up a couple tanks :)

Bean Animal Overflow
The Bean Animal drain is a hybrid version of the Durso and the Herbie drain and literately employs both drain styles to accomplish high flow rates while operating near silent.

In the diagram above you will notice the Bean Animal Drain uses three drain lines which means you need three holes in your tank or overflow box. The main siphon drain is a Herbie style pipe, the secondary vented standpipe is a Durso drain and the third is the emergency back-up drain.

The reason this drain operates quietly, even with high flow rates, is because you can reduce the rate of flow using the valve on the main siphon drain to the point it operates silently. The Durso pipe then drains the additional water required to accommodate your desired rate of flow through the aquarium. With the Bean Animal, the two drains would be submersed below the sump water line for effective, clean, and silent operation.

The end of the emergency drain can be cut above the sump water level. Should it ever be in operation, the splashing into the sump will act as an alarm, alerting a hobbyist that something is wrong with the drain.

The Bean Animal is one of the best ways to move water out of your aquarium and into your sump. It is quiet, handles high flow rates, and includes an emergency back up drain. The downside is the amount of space required to get all three drains installed onto your tank.
