Help Me To Stop The Noise

Wait are both drains, or is one a drain and one a return? The open-topped one is obviously a drain. Adding Durso hardware on that will definitely quiet that one down

The open topped one is the overflow, and the other is the return, the drain is just like a plug hole on the bottom of the tank with no pipe at all

Completely agree about the durso, it really quietened mine down when i changed to using one.

Here's an example:

I think in this case the overflow is only used when the tap on the drain gets out of balance, ideally you adjust the tap so the water is as close to the top of the overflow without going down it. I think that's what it's supposed to do??

Using a tap to adjust the flow of an overflow is a very very bad idea IMO.

Anything that narrows the pipe is a the perfect place for something to get stuck and as such is a recipe for disaster. If it was me (and this is exactly the position I was in) I'd remove the tap and add a durso.

As I understand there are three ports in the weir, 1 return, 1 overflow and 1 Drain, thereby allowing you to adjust the tap in the drain to the perfect level and if it goes wrong the overflow takes over.

I would agree with you if the overflow wasn't there as a backup, but if the drain tap can result in the perfect level most of the time I reckon this is the perfect system, as you are not sucking air in down a pipe you only have to deal with the flow from the bottom of the tank to the sump...
