New water Pump noisy

[adonh]

I fainally wa s able to fix the sucion line problem from the water tank and install the Jabsco Sensor MAX VSD pump in my 1976 A/S. Great pressure at all outlets and no leaks. But the pump is noisy. Vibrating from the time it come on unti it shuts dowm. It seems to be right at the pump. Any thoughts

There are some nice threads on the forums about quieting pumps. Rubber floor gaskets, accumulator tank, insulating the hoses so they don't transmit vibration, etc.

ShurFlo Extreme Sensor 4.0 or 5.7 model....depending on how fast you want to empty your fresh water tank! These are the only pumps I install.

Hi Lew,

Are those pumps quiet? How's the reliability? I seem to recall when they first introduced them, that a lot of people had problems.

Thanks,

They come with a 3 year factory warranty and both are variable speed, so they run very quiet at low water demand and ramp up with increased usage. I've installed 13 this season and have not had one complaint yet.

Go to the hardare store and get some hose clamps. The ones that encircle the hose, have a tab with a whole. Secure the water lines to and from the pump. This should reduce the noise. I had my output water line banging against the floor.

I tried the clamps and other things. Still was noisy. So I disconnected the output line going to the trailer and connected another hose with a hose end faucet. Then connected a water hose to run out side. Still noisy so that eliminated the pex and other possible vibrating in the trailer. I then took the pump out all together and hooked up a short suction line to a bucket of water. Still noisy. I took off the "Pump Guard" filter that came with the pump and hooked up the line direct. Not as noisy, but still not quite like it is supposed to be.

So I think it is just the pump. This is the Jabsco Sensor Max VSD that should be comparable the to the ShurFlo sensor 4.0.

Are you saying you have hard lines to your pump?

[adonh]

No from the water tank is a rubber hose with stainless steel spring wire inside so that it will not collapse. The output side connects to the pex pipes that run through my trailer to the fixtures. I also tried a short rubber hose from the pump connected to the pex, but still noisy. As I said even with the pump out and pumping water from a bucket its still noisy. I think it must be the pump.

This months "Trailer Life" suggests bolting a noisy water pump to a separate board. Then apply a layer of foam or other vibration absorbing material under that board. Then gluing the foam surface, not bolting, to the floor.

That's what I did, it helps, but can only quiet it so much.
