loudest water pump this side of the Mississippi

Just past a year with our first travel trailer. When we dry camp or boondock, I am AMAZED at how loud the water pump is. It shakes the whole 30 ft trailer. Is this how ALL water pumps are? Just loud and annoying?

This is on a 2018 Kodiak 255BHSL.

YES! :0 there are several ways to quiet them down and they really work. Changing several inches of the hose that connects to the pump with softer rubber helps immensely. Putting a new rubber pad under the pump where it bolts on also helps. You will be sleeping through the pump up in no time.

Here's a video of what I did to get it to quiet down.. (this isn't me)...

That's an easy fix, just camp on the other side of the Mississippi!

Frank has posted a good fix for the usual issue with noisy water pumps. There are other possible contributors to the issue.

There is a check valve in the pump or line to the pump that prevents water from flowing back into the fresh tank. That valve becomes a little sticky when it is not used for a while. Two or three days of use usually loosen it up and it quiets by itself. Or, it could need replacing.

All the soft or hard pipes can vibrate against anything they touch. Padding them can improve things. Installing a tiny pressure tank in the output side of the pump can greatly soften the noise. The hot water tank in my TT almost always has an air bubble in it at the top. Even when my cold water pipes are making a lot of noise due to the sticky check valve, the hot water pipes rarely do or do a lot less.

Our pump switch is in the bathroom, so at night we just turn the pump off, or on and off if toilet needed

I can agree with the longer it sits idle the louder it can be. Went on our last trip this weekend and used the pump for the first time in months, Yeah, it was louder than usual but quieted down after a few flushes.

We too have a noisy pump. Not ear splitting but worse than it should be.
Removed panel and took a few pics:
First question, is this type of hose worth replacing to get any reduction in noise? Not what I would call rigid at all but perhaps not as flexible as might be.
Second, I think possibly cushioning the hoses where they contact framing and other components would help.
Third, pump itself has hard rubber feet and seems designed to move a little independently of those feet - presumably to reduce vibration noise. Would putting further cushioning under the feet (such as rubber bushings) or under the body of the pump help reduce the noise?

Any thoughts appreciated.

Researchhound: To answer your questions I think it depends on the cause of the issue. I also have a loud pump, but it seems to quiet down considerably after I run the water for 1-2 minutes. I did try the things you listed trying to solve my vibrating pump.
I purchased one of these silencing kits and attached it to the pump.
https://www.amazon.com/SHURFLO-94-59.../dp/B000WN5F96

Than I took an old mousepad and put it under the pump.

Then I got some cheap insulation from the local hardware store and covered my pipes where they were touching each other, the floor, wall, etc.

It helped quiet it some, but I think my cause must be getting air into my water system.
I haven't quite figured it out yet, but since I did the above 3 things, I still get some loud vibration. It seems like after I fill the fresh water tank, the system is loud. After I run the water from the sinks for 1-2 minutes, it quiets down to what I would say is "normal" (based on my last trailer pump).
All 3 things you mention are cheap and worth a try.
Good luck.

First I bought one of these "silencing kits" https://www.amazon.com/SHURFLO-94-59.../dp/B000WN5F96

Then I took an old mouse pad and put it under the pump.

Finally, I got some inexpensive foam insulation from the local hardware store and wrapped it around the pipes where they came in contact with each other, floor, wall, etc.

All of these were pretty inexpensive and worth a try.
Depending on the cause of your noisy pump they may or may not work.
They really did not work on mine and I have started to think I must get some air in my lines when I fill my fresh water tank. After I run my sinks for 1-2 minutes my system quiets down considerably.
Hope this helps and good luck.
