If you are finding your RV water pump seem noisy or is getting noisier, there are some simple things you can check:
1) Is the mount on your water pump tight? Sometime the vibrations can loosen the screw holding the pump itself allowing it to move and bang on the surface it is attached to.
2) Are there rubber pads on your water pump? Most water pumps are attached with some rubber padding between the pump and the mounting surface, allowing for vibrations to not be transferred to the RV itself. If that seem missing or in disrepair, fixing that issue can be a dramatic improvement.

I’ve seen pumps mounted to thin, hollow cabinet sides that created a drum effect when used, amplifying the sound. In these cases, repositioning it to something more sturdy, like the RV sub-floor, will help significantly.
