Loud water pump

Previous trailer, I did all I could to quiet down the pump. I put foam rubber under the pump and then screwed it down, but not tight, so it kind of floated. It helps a lot. Still make sound though.

Current trailer? OK, it makes noise, but who cares! It's part of the camper, and everyone in the camper knows it's a necessary noise, so they just have to live with it. Problem solved. Who cares! I'm not busting grapes again to quiet it down.

And? even with full hook-up sites, we always use our fresh water tank and on-board pump. I fill the tank from the available water source and turn off the source. Why? There is never any concern about over-pressurizing the camper's water pipes. When connected to "city water" you just never really know what the pressure is. So, to be safe, we just use the on-board pump, even at home in the drive way, where I know what my water pressure is.

Noisy pump? I'd tell everyone to just live with it or they can just go to a motel! Problem solved!

I want to know when it's running, in case of a leak.

I made a "foam sandwich" to mount my pump on - plywood on both sides of 2" of soft foam put together with construction adhesive. It made only a little difference and, in retrospect, padding the hoses is what needs to be done. That pex is pretty hard stuff and will rattle up a storm if it gets next to or up against something.

Thanks guys that all makes perfect sense. Yea you're right I guess you should know that it's running.

Water pump noise is usually causesd by the hard lines resting against a wall or some other hard surface. If you can figure out where it's doing this and put a piece pf pipe insulation around the pipe it will make a world of difference.
They also make "quiet kits'" that add a length of flexible line to the input and output of the pump. I've never needed one of those though. just stopping the pipe from rattling against things has worked for me.
