I would like to isolate my water pump as it is bolted to the trailer floor and vibrates when being used. I have added an accumulation tank so it doesn't run so often but I would think that by adding some method of isolation from the floor, it would not be so obvious when running. Anybody have any good luck with rubber grommets, isolation boards, etc?

I made it better, but not absolutely quiet....I don't think that's possible.

Mount the pump to a board and isolate the board by placing foam under the board.
Place foam between the water lines and any contact points.
That should help, if not cure it.

This SHURflo Pump Silencer may help too. I did the same thing by going to Lowe's and getting some flexible faucet hoses and adapters.

I have a ShurFlo Whisper King pump. They cost a couple of bucks more, but mounted to the floor, under the goucho in our Caravel, it is smooth and quiet. Very quiet. There is almost no vibration in the system.

Love it.

Mounting a layer of EPDM rubber under the base can lessen the vibration significantly.

I used a mouse pad from my computer - works like a charm.

Also, the Shur-Flo pump silencer that COSMOTINI recommends is good - the pump manufacturer recommends flexible tubing at the pump - the AS factory uses rigid tubing. This kit goes on in less than half an hour.

Best of luck!

A lot of my noise came from the output line bangin against the floor. I restrained it and the noise significantly reduced. My output line already was a flex line.

Here's the solution I used in our previous SOB...attached 10' of coiled high pressure flexible tubing on the output side of the pump to absorb the pressure wave before it hits the hard PEX tubing, and remounted the pump on medium density flattened hot water pipe insulation. Total cost $10 bucks.
