Took my 'new to me' 2010 Kingsport 301TB out for it's first trip this past weekend. I was very annoyed with how loud the water pump is in this unit. Considerably louder than in my last TT (A Palomino). Does anyone have any advice on how to quite the existing pump? Failing that, I may have to purchase a new quieter pump.

Noise is usually caused by the pump or lines vibrating against something. Barring that, there are quiet kits you can add to the pump that come with two very flexible lines for the input and output of your pump.
I suspect that if you follow the lines you'll find that by holding them away from something the noise will be tolerable. I had to use pipe insulation in a couple of places to stop the vibrations.

It could be that your Palomino had the bigger more expensive quieter pump!

My water pump in my MH was quiet and had great pressure.
Never did understand all the posts about loud water pumps.

Well my pump finally died and mobile repair came out and replaced it.
The new pump was like a freight train going thru the RV and when I turned the water on it shook and stuttered all the lines. Called the mobile repair guy back inside the MH and here is what we discovered.

My MH came standard with the bigger water pump that costs about $200.00. The mobile repair guy replaced it with the ole standard pump that costs around 65.00.

It's loud and I had to remove all my nice new sprayer heads I put on all the faucets because the the smaller pump pressure is just too low enough to make it thru the spayers without shuddering.

I bet your Palomino had the larger pump, my Palomino Thoroughbred TT came with the larger pump.

I think what size pump is installed is something that needs to be put on everyone's "what to look for" list when buying an RV.

That's what we did. Worked great!!

If it's a fast hammering noise you hear it may be the piping vibrating against something next to the pump and not the actual pump. The pump may be cheap (like most are in new RV's). If you change it out get something like this. It's expensive but, you get what you pay for.

We used our water pump for the first time since installing an accumulator tank this year. WOW what a difference in noise. I had to shut off the ceiling vent fan to hear the pump!!!

Great mod!!!
Search for accumulator pump install and you'll see lots of options.

I learned on this forum that many have removed the first foot or so of piping after the pump and replaced it with the metal flexible line with connectors on each end (hardware store has them). Put the flex line in an "S" shape, not straight. And put padding around that. The rest of the piping will not vibrate against things anymore.

Last night I went to Lowes and purchased similar parts to these except 30" hoses plus plumbing tape for about $18. The 1/2" connectors are near the sprinkler fittings.



Once attached, I still had about half as much noise which I wasn't satisfied with. I then took cable ties/zip ties and tied hoses together and to the pump in a way that had them avoiding contact with the walls and floor. This eliminated half of the remaining noise for a total of about 75% decrease (IMO).

I'm still not completely happy but it's a heck of a lot better. I'm hoping the result will be that people can use water in the middle of the night without waking everyone.

In addition to the flexible lines, I screwed my pump on top of an old mouse pad and that helped buffer some sound.

I have seen somewhere, probably on here somewhere, that someone made an insulator that went between the pump and the floor. He made insulator out of 1/8" plywood on each side with some foam, like a couch cushion, sandwiched in the middle. Looked like a big sandwich. Mounted the pump to one side and the other side to the floor. To me, it sounds like a great idea. I have yet to try it since my pump is noisy. I moved some of my lines around and that helped but I guess we are all spoiled by our regular houses not having pumps.
