Hello HomeDepotCustomer and thank you for the feedback you posted on the Home Depot website. We are sorry to hear that the Moen GX50C Prep Series 1/2 HP Continuous Feed Garbage Disposal with Sound Reduction and Universal Mount did not meet your expectations. The noise level of the disposal will be influenced by installation conditions. Because of this, perceived noise levels will vary. Due to the powerful vortex motor and torque this disposal deliveries, you may experience a louder noise if the disposal is being run without food or cold water. When the disposal starts, the impellers will swing into position to guide the food to the grind ring. When they hit the grind ring, you hear this noise. Our product specialists are available for pre-purchase, installation and warranty assistance. They can be reached at 1-800-289-6636 and are currently available Monday through Friday from 8:00 am – 7:00 pm Eastern Time.
