Noisy water pump on Damon Daybreak

We are new to owning a motorhome, but it has been our dream for many years. Bought a 2008 Damon Daybreak and are learning slowly all the little tricks of using it. One of our concerns that took us back to the dealer was the noisy water pump which sounds like a miniature jack hammer every time the water is turned on. We were sure this couldn't be right, but were told, yes, that is how the pump sounds. It can be heard outside the MH 100 feet away! Since we do get up in the night for bathroom needs, I feel badly for anyone camped near us with this awful sound. Evidently we can buy a quieter pump. Is this our only hope?

You could mount it on rubber isolation pads:
Vibration Isolators | Vibration Pads | Easy Cut Waffle Pad - Natural Rubber 8" X 8" X 3/4" | 238154 - GlobalIndustrial.com
or mounts:Cylindrical Vibration Isolators Rubber by VALUE BRAND - Cylindrical Vibration Isolators by Zoro Tools Industrial Supplies

add flexible hoses going to and from the pump:
SHURflo Pump Silencer Kit - Hypro-shurflo Llc 94-591-01 - Pumps & Tanks - Camping World
sometimes it is necessary to even add a water hammer arrestor like this one:
Shop Sioux Chief Water Hammer Arrester at Lowes.com

Good luck and hopefully you'll be able to rest easy!

many times the jackhammer sound is not actually the pump....it is coming from the water lines somewhere which are not insulated or secured properly...they pulsate from the water pulses inside the line...the line then bangs against an inner wall (for example) and magnifies the noise. I dealt with this in a toy hauler...I insulated the pump mounting...no help...I installed the rubber flex hoses from the pump to the hard lines...this helped some but not completely...short of tearing out a bathroom wall to insulate and properly fasten the water lines..I was out of luck.
Now with our new to us RV...the water is so quiet...I cant tell if pump is running...and kind of miss the banging...at least I knew water pump was working..lol

1. add flexable lines to each side of pump.
2. use foam pipe insulation to isolate hose from walls and cabinet panels.
3. add accumulator tank, may not help that much with noise but will stretch out times betwen pump runs
4. If still a problem like I had check my mod. at Damon mods
now we can hear it just enough to know it is running

You can hear it 100ft away? Really? With the water compartment door closed? Doesn't sound normal to me. Maybe show the dealers tech what it's doing? I have found with mine that when the tanks water level gets below 1/4tank that it does sound a little louder inside, but outside it's still pretty quiet.

I have noticed that new owners often notice the sound of the pump inside the coach, but outside, with the water compartment door closed, it's usually barely noticeable. Having that sound inside lets me know that the pump is running properly.

Good luck with the dealer though. They hear this complaint all the time from new buyers when there is nothing wrong so they generally wouldn't want to just swap out your pump. You'd probably have to prove to them that it's much louder then normal.

We had a 2005 Winnie, pump was pretty loud, but I figured normal.

We bought an old 1992 American Eagle, kind of loud but not loud as the Winnie. It had a leak in it and since it was original to the coach hubby decided to get a new one. I said well get a quiet one. Now I can't even hear the durn thing, and can only tell the pump is on because I have water, I wish it would make a bit more noise so I can tell when its on.

Don't let anyone tell you you can't get one that is quiet. But then this old coach is pretty solid so that could be why too. Hubby just fastened it to a bay wall near where the old one was.

We had a noisy water pump and discovered it was from the filter being clogged. After we cleaned it we could hardly hear it anymore. Hopefully your fix will be as easy.

Try one of the variable speed water pumps. These have been around for a few years now, the difference in sound is very significant, and I think they are worth the money.

This won't work if your pump is mounted on a wall, but if it's mounted on a floor or horizontal surface, you might try just removing the mounting screws all together. The pump's not going to go anywhere while fastened to the plumbing...

The noise reminds me to tell the DW "SHUT THE WATER OFF"! She just doesn't understand the concept of water conservation.

CW sells a pump quieting kit for $30 that consists of 2 short flex hoses.

FWIW I just upgraded to a Surflo 5.7 gpm pump and the instructions say if you have a accumulator tank to disconnect it. I bought the quiet kit and it consists of two pieces of the same hose my pump was plumbed with. The instructions said it would take a little while for the pump to break in. I thought that was kind of wierd. Sure enough after a couple of one week outings it is quieter and the flow is smoother.
