Members,

Try as I might, I cannot get our 12-volt water pump to quiet down. I've searched the Thor forums for help but didn't find anything.

Our MH is a 2013 Thor Four Winds 31F and its design puts the extremely noisy 12-volt water pump (you guessed it) right under the head of the bed!

I've thought about getting a new quieter 12-volt pump, but it seems to me that the present pump isn't the main source of the noise, it's the rattling of the pipes that lead to the wash basin and shower (but not so much the galley sink).

What do you all think? Should I try to reduce the vibrations and thumping by tying the lines down more securely, or should I do the opposite and let the lines "float" cushioned on foam supports?

I've checked and cleaned the pump's wire filter (which wasn't all that dirty); I've opened and allowed the water hammer tower to breath; but to no avail.

Any suggestions would be most welcome.
