Flexible rubber hoses, about 2-3 feet in length, from the pump inlet and outlet connections and then connected to your present hard tubing will cut down on noise considerably. Basicly you will have pump, rubber hosing, and then your present PEX tubing in that order. Since its flexible I just made a coil (loop) in the flexible hoses. Alot of the pump noise that you hear is from vibration being carried thru the hard piping. The flexible hoses calm that vibration down a lot.
