Well guess what? While on the tank side of the pump Trailmanor used a nice, soft plastic tubing with braid reinforcement, on the other side the pump is attached directly to the hard plastic plumbing used throughout the rest of the water system. I bet that's where the noise is coming from. All they needed to do was put about a foot of the soft stuff between the pump and city water input tee. What were they thinking? I guess they just weren't.

I have a fair amount experience with the water pump. And in fact, I have an identical model as in the TM that I use as a water transfer pump, as it actually used to be installed in my TM where it made a racket. When held in my hand, the pump I use as a transfer pump is not quiet silent, but very quiet, when in use. The difference? Yes, if you replace the PEX with flexible reinforced tubing, that will do alot to reduce the noise. But be careful not to create new high points in the plumbing that would prevent water draining when you open the drain valves. That is my guess as to why TM doesn't use flex tubing -- the high points are harder to control.
It would also be of great benefit if you mount the pump to a shock absorbing pad -- something like a thin sheets of plywood with a piece of semi-rigid foam or rubber in between. The one sheet is mounted to the wall, and the pump is mounted to the other sheet. The screws mounting the pump should not extend far into the foam, as they will transmit the vibration.
If you do these 2 things, your water pump will be VERY quiet.
