Wow, Soundguy. That was an incredibly effective solution. How do you have the piece of plywood mounted to the sponge, and how is the sponge mounted to the floor?
The pump is mounted to a piece of plywood with four screws that extend down into the foam, as well as some carpenter's glue between the wood and foam. As I recall I also just put a dab of glue on the underside of the foam to secure it to the floor but that's not really necessary as the pump with the hoses connected to it really can't go anywhere anyway.
FWIW, we've owned numerous campers over the years from popups, to a hybrid, to travel trailers and I've tried all the usual pump silencing methods everyone else has tried - different pump, isolating the pump, foam pipe wrap, securing water lines with nylon cables ties, adding an accumulator tank, you name it BUT none of them,even in combination, has ever been anywhere near as successful as
significantly extending the length of the output hose
before it interfaces to the trailer's hard wall PEX water lines.
