2011 3000RK Sundance: Pulled at of the panels out of the basement to install a 50 amp surge protector and saw how the water pump and plumbing was installed, not a pretty site, my week covered all areas, electrical, plumbing, HVAC. Anyway our pump made quite a bit of noise especially when you were in the bathroom. Found the pump not to be mounted to the floor, fixed that by mounting it on a 2x6 still made noise, watching it run it became clear that it was the pex tubing shaking when the pump cycled. Completely redo on the lines in and out, went to plastic hose which is much softer than the stiff pex tube. Tried it at first with a straight piece of hose into the pump and did not help much, old gas services trick, added a loop in the hose into the pump and insulate as much as you can get to. The noise is really reduced, you can still hear it in the bathroom, not near as loud as before, but when you are right next to it in the basement you can hardly hear it. From the kitchen you do not know the pump is running. "Sweet"
