Yes mine was about to "wake the dead" as well. When it reached full pressure the slapping and banging of the hoses against the wood was like a hammer on a drum. Having a piece of flex hose on the pump on the way in and out helped as well as the foam.
It can only get better from where I started....
However I did have a problem where I sucked an air bubble into the pump on a low tank. Still with almost 5 plus gallons of water in it. Since the pump dry locked, it just kept running, and running , and running. It happened when we where not in the TT. When we came back the smell of hot motor insulation was a very scary thought. From this "learning" we always now turn the pump OFF when we leave the inside of the camper.
Out of this I also upgraded to a variable speed pump. WOW what a difference in both noise reduction and performance. Any new TT I get, I will insist on a variable speed in place of the standard pump. I went this route verses the accumulator. I also fixed the tank suction setup to not suck a air bubble with still 5 gallons of water inside. The problem is the suction fitting they used.
Sunline used the fitting in the side of the tank where the water is about 1" to the top of the fitting. So when water get's to ~less than 1" across that entire tank, the pump can suck air from above the water line. So I used the low point suction/drain port. There is even a mesh screen inside my tank in this location. Since I filter all water into my tnak, I do not worry about any sediment issues and I installed a filter/strainer on the pump suction that was not on my the original Sunline setup for reasons I have still not figured out. Shurflo recommends the inline strainer. Don't know if they just plain missed it on mine.
I'll post here in case any of this helps you or other fellow campers with water system banging.
The pump suction fix. I can now draw down to only about 1 quart left in the tank. Makes me able to go another day on a tank.
And here is the Variable spped pump upgrade.

Good luck and let us know how you made out.
