return pump noise when fully open
Hi
The set up is a Mag 12 with a 1" return that splits into a 1" return and a 3/4" loc line There is lots of flow with the return valve (after the pump) fully open but I get an annoying sound. If I partly close the return valve the pump just hums nicley. I don't want to reduce my circulation though... What is causing that noise? I'll will make a video to show what I mean. cheers |
