Noisy water pump

[frydaddy]

What would you put around the fresh water pump to eliminate the noise?

A couple of things you can do to quieten it down. Put the pump on rubber isolation. i.e. don't mount it rigidly. I used a couple of pieces of rubber hose with one wall fastened to floor and pump sitting and fastened on top. Also, if your pex tubing is connected directly to pump, it will vibrate noise thru the tubing. You can isolate that also.
Take a look at my mods post # 1. http://www.thorforums.com/forums/f27...-mod-2255.html

Usually it not the pump, but the PEX lines that are hard mounted to the pump that make the noise. The pump is mounted on four soft rubber blocks so there is not much else you can do with the pump. If the pump is mounted on a thin piece of plywood, a small section of 1/2" plywood under the pump and on top of the thin original mounting position might help. Shurflo males a kit to quite down the pump. <https://www.amazon.com/SHURFLO-94-591-01-Pump-Silencing-Kit/dp/B000WN5F96>. An accumulator also helps quiet the pump noise. Finally you probably have a constant speed two piston pump. Several companies market a five piston variable speed water pump all will be a little quieter than what the coach's original pump.

I'm just happy to hear that it's running (and working!).
