ok I found out the problem, real simply turn your pump on and remove screws which mount to the pump, then while the pump is on hold it from the bottom and then raise it up, the pump should be quiet then, because of all the vibration and motor turning causes the pump to have loud humming noise, I might have to mount it on the floor to have solid contact so no vibration can occur, before pump was mounted on 3/4" plywood frame with 2x4 but that didn't do the job, hope this helps
