Quiet water pump?

It has been a while since I have posted in here because quite frankly everything is working pretty well on the ACE.
One thing that did get me thinking though is about our water pump.

We just came back from camping and I wanted to run the water out of our holding tank so we used the pump for 2 days. The problem is that late at night when someone went to use the bathroom, everyone was awakened by the water pump!

Does anyone make a 'quiet pump'? Ours is very loud and vibrates the motorhome.
Or did someone design a way to isolate the pump from the water compartment.

This worked for my Bud....


You can also use a high density garden kneeling mat under the pump if you can get to it. It will damp vibrations. They come in snappy colors.

Ours was mounted on a thick hard rubber 'block', I suppose to minimize the noise, but the block only serves to reverberate the sound and feel even more... so, I unmounted the Pump from the rubber block, inserted a silicone rubber 'doggy bowl' (or some type of thick foam rubber item), and just SAT the Pump on top of it.
The Pump now CAN NOT be heard, or FELT, within the coach anymore... nice.

so simple, sometimes I wonder why the factories have a hard time understanding that simple is better.

Sure. Just buy one of the variable speed pumps from FloJet or Shurflow. these are about twice the cost of a cheapy pump, but very quiet and free of vibration. They will provide smooth water flow from a trickle to full force. We have used these on our current and past Safari TREK.

My experience has been if there is air in the lines, then the pump will be excessively noisy. The way I have resolved this is to run city water to all outlets to eliminate air and then keep a fair amount of water in the tank which maintains a higher head pressure to the pump. My pump and tank are on opposite sides of the rv, so a higher head pressure is helpful in preventing air from entering the suction side of the pump. Doing all this makes this pump the quietest I've had in 3 rvs. No one woken up in the middle of the night anyone. Hope this helps.

A cheap pump will make a lot of noise as it cuts in and out. I put an accumulator after my water pump and it smoothed out the water flow, both on the pump and on city water. Still not as quiet as a good pump though.
