My water pump was loud as well. Apparently, the pounding in my water system was caused by the water pump raddling the input pipe from the Fresh water tank. I inadvertently corrected the problem when I installed a city fill modification to allow me to fill the freshwater tank from the city connection instead of from the gravity fill located on the opposite side of the coach. As part of that install, I also installed a support bracket. I used a residential bracket designed to prevent pipe pounding. You can see it just below the ball valve in the attached photo.
If you can find the pipe that is pounding you can install one of these to stop it.
Here is a link for the support bracket:
