Loud Water Pump

[K3WE]

We have a new camper and the water pump really resonates on the floor. I think the pump is fine, but it's bolted to the floor under the kitchen sink- and vibrates just right for the floor to really amplify it.

I've got an idea or two to put some padding between it and the floor, but would also like to see if other folks here have come up with some brilliant solutions.

Thanks.

If you are fit enough and got the urge might be able to make a separate mounting board mounted it self with big thick rubber bushings to structure and then mount the pump to it with bit thick rubber bushings and a loop in the hoses on both sides of the pump. Don't let them ump anything either

Coming the marine trades and such, this was a constant worry. More than once, sitting in the main cabin someone would hear the potable pump rattle and jump up to find the errant tap.

That is another reason It doesn't bother me. Nice to know that if you hear it running there is an issue.

I also like to hear the water pump run. That burp when there is a slow leak someplace saved a bathroom floor recently. Also turning the pump on after being gone for a while and hearing nothing is a good feeling.

Now rattling water pipes just have to be quieted somehow. Been there, done that also.

Nothing quieted mine... I bought a brand new unit, 75% quieter. An accumulator quieted it to 90%. Can still here it if I listen for it.

Been tempted to take the old one apart and see if Some debris got into it.

Ditto to Old Biscuit. That will cure 90 percent of pump noise issues.

I can hear mine...and maybe it's loud. Dunno. Doesn't bother me.

I like the idea of hearing it just in case there is a leak or a tap wasn't shut off properly.

My water pump makes the rat a tat tat until 100% of the air is purged out of the system.

One persons really loud is normal to another. Check the pump mounting. A bit of foam backed carpeting might reduce it. Check those pipes too. We use our pump 100% of the time. Fill the tank through a water softener then use the pump. It makes different sounds for different reasons. Kinda letting me know how it & my water system is feeling.

On my TT it was also bolted to the floor, but it was mounted to a flexible rubber foot. Mine was loud also. I never really bothered with it because we only dry camped about 3 times in 13 years. What I did notice was although the pump was mounted on a flexible mount the water lines were rigid mounted. If I were to quiet it down I would've cut the lines back and looped flexible lines so it didn't transfer vibrations. However i fixed that by buying a class A with the pump mounted down in the storage compartment. Now I can barely hear it,

That was my $65k fix!

Sounds like the 'Factory floor monkey' way over tightened the pump mounting screws

The rubber pads under the mounts should NOT be flattened/.over-compressed
Mounting screws should be SNUG ---just enough to hold water pump in place

Loosen those mounting screws then just snug them and give the pump a test run
With oump running lightly tighten each screw slightly if still vibrating

Also check the routing of the discharge hose which should be flex tubing vs rigid PEX pipe

Here's my "brilliant solution" ... 2 pics, 1 video. Pump operation is so quiet I had to add a light to the pump circuit so I'd know when it's running. Click "i" at the top right of any pic for a text description.

It's usually water lines that are up against hard walls and floors vibrating that makes most of the noise and not the pump itself. I would look for those spots first and use pipe insulation or foam to isolate them from hard surfaces.
