Just wanted to ask people here, but how loud should the return pump and the overflow be? Cause it's quite loud now. The Mag 5 pump vibrates quite a bit an there's a loud hum coming from it. Not sure if there's something wrong with the impeller, but I think that may be the cause... maybe it's unbalanced or something.
The Glass Holes overflow is loud too. I think my flow rate is a bit low for the overflow. I tried stuffing a wad of paper on one side of the drain, and the overflow itself decreased in noise, but the elbow and drain is loud too. I'm using flex hosing instead of rigid PVC
, could that be the problem?
Thanks for any help.
