I had a noisy pump in a 5th wheel I had. The pump mounted to the floor so I added a rubber pad under it and I added an accumulator tank. It really quieted things down and at night the stool could be flushed several times without the pump coming on.
Having three truck campers and later three 5th wheel rv trailers some pumps were very noisy depending on where and how they were mounted.
I had all types of rubber pads available at work that all had different durometers. From the trash bin I chose a 1/2" thick soft 40 durometer the size of the pumps mounting surface. This cut pump noise 300 percent to super quiet.
The accumulator water tank eliminated constant pump cycling.
Some of the pumps were mounted on a wall and weren't as noisy. My noisy ones were mounted on the plywood flooring.
