I installed a reefsavy ghost overflow on my new 240 build. But the problem is how LOUD the water is flowing down the drain pipe down to the basement sump. I also installed a 1” tube in the hole in the main overflow pipe. Please help as this thing is LOUD. Main drain has the valve on it

The lower I can understand is to clear the valve but the upper one?
