As Stiles stated rubber feet and a piece of flexible hose in the water lines do help. When we got our Monty I kept telling our dealer it was the pump making the noise. He installed the rubber feet and flex hose. Not much improvement. He insisted it was just the nature of the beast. I knew better as our other trailers were never this noisy. I finally changed the pump on my own as I had a spare from our previous trailer. Guess what? About 80% of the noise was coming from the original Monty pump. Sometimes you just get a bad one.
