To the ORV owners out there, any remedy for a noisy water pump. Have tried the foam route underneath, and have checked all connections. Sounds like the pump is cavitating due to lack of water, but the tank is full and the filter at the pump is clean and the bowl is full. Any suggestions???

Mount it on thicker plywood. Add an accumulator tank. Add long, flexible hoses.

adding 12-18" more hose worked for me, you will need to replace the hose with one the same length as the old one PLUS the 12-18 extra inches,
DON'T Splice them together.
the sound is from the vibration of the pump against the wood from a Short Stiff hose.

Since the pump sounds like it is cavitating, I would look very closely for a loose hose connection between the water tank and the pump inlet. You could test that by temporarily replacing the inlet hose and draw (suck) from a gallon jug. Or, easier yet, use your winterizing setup and see what it sounds like.

Good luck!

All things water or anything else for that mater.

I think it needs some directional arrows and a "Watch for Snakes" sign...

Is this a bowl of spaghetti! Poor design !

Wondering where your pump was physically located?

Need to locate the one in my windriver. But think its not easily accessible

Try one of the variable speed water pumps. Can't remember the model, but both water pump companies make the products. I have installed these in the current and previous motor home. Very quiet, no surging, around $100, but worth every penny.

Good humor guys! While I don't have an ORV, my trailer had similar problems. I first tried the pump silencing kit http://www.amazon.com/SHURFLO-94-591...=shurflo+hoses

It made only a minor improvement. I then tried to insulate the existing hoses/pex around the pump (quieted down even more). Then i realized the noise was coming from the pex pipe vibrating against the trailer frame some distance from the pump. So I put pipe insulation inbetween the pipe and the wood frame. (more improvement)....then I realized the part that continued to vibrate was inaccessible and I gave up. The answer would be to hold up the pex and slide some insulation over the pipe from where I can access it back up to where it is hidden.

That gets me to the comments about Lynnmor's post. Not sure about your access to the water pump area but mine was extremely limited. Yes I would like to make mine a neat and clean install but there just isn't enough room for me to get in there to work on it and the hose lengths are not conducive to a clean install. I had a very difficult time just routing the silencing kit to ensure the connectors were not stressed, let alone it looking nice. So lynnmor I share your pain here.

I just learned to live with it. besides I only use the pump when winterizing or de winterizing or if I need to use the facilities at the storage yard.

when or if the pump fails one day I will beef it up and make sure its whisper quiet....
