I have a brand new 2013 Road Warrior that is on it's maiden voyage. The water pump was making a terrible racket. After locating the pump, discovered water dripping on top of it from a leaking drain pipe at the bathroom sink. The attachment area was very wet. I lifted the pump off the deck! The screws fastening it down protruded past the bottom of the mounts by only about 1/4"!! I wiped the water up. Tightened the plumbing fitting, and placed a fan in the space for several hours until it was dry and refastened the pump with long screws. Noise level significantly reduced but still loader than any RV I have had before.
