Nnoisy waterpump on a Swift 630, 2006 model (1 Viewer)

Hello everyone,

We are out at Los Madriles with our friends who own a 2006/56 Swift 630. Their water pump makes a loud juddering noise when any tap is opened, or when the loo is flushed. Any suggestions as to what the fault may be?
Regards, Gary

Probably that it's a diaphram pump as opposed to a submerged one that you have in your Hymer.
All tend to be noisy,but check the mountings & that no part of the pump is touching any part of the body.

Thanks, and you are right it is a diaphragm pump. I will pass that on and let you know how it goes. Gary

Always amazes me why converters use diaphram pumps, they're always noisier & seem to be 2 or 3 times the price. A twin Reich pump & pressure switch would be much better.

Hi our pump in our swift 630 that we had for 9 yrs was always loud we never noticed how load really though till we had the hymer . It's the way the pump is our pump never gave us any probs In the 9yrs so it must be the design of them .
regards Kate

I'm a fan of a diaphragm pump.
Immediate flow when you open a tap, positive displacement operation which pumps air to clear your pipes on draining down, and an audible indication of your water system has a leak!
What's not to like?

"Noisy" R-V pumps per-se are more often due to BAD mounting practice. Mine in the Rapido is in a recess on the top of the Tank!! would you believe, sitting it on a big "Drum" in effect, I can see that getting changed soon too!!.

When we had the Bolero I remounted the pump on rubber grommets and it was much quieter.

And that's what my friend has decided to do. Thanks for the advice. Funnily enough. The day after I posted this an Italian couple pulled onto the next pitch to us in a very handsome Giottoline A class. Beautiful van. Then I heard him switch on his water pump - exactly the same noise! Today is my birthday so I,m starting with a fifty mile bike ride round the Puerto Mazarron area and if I have the energy left, we have a table booked at a new restaurant just this side of La Azohia tonight. I keep telling all my friends that you can't beat MHF for good, swift advice when you have a problem. Thanks everyone, Gary

Old engineering trick
Do not use rubber but cork.
Cork has a much higher isolation factor than rubber

Got that, thank you. Gary
