The 5.2GPM pumps we sell are noisier than 3.5GPM or below pumps. This is due to the sound caused by the motor and water circulating in the 4 chambers. But there are still things we can do to reduce noise, such as standard installations. We recommend fixing the rubber feet to the wall or countertop with screws, which will reduce noise to a certain extent.
