Hi All, the diaphragm pump for the water system drives me nuts every time it operates, really noisy. It is fixed to a board under the saloon seat. Any tips/advice on how dampen the noise? thanks RPP

I assume it is mounted on the rubber dampers? These should not be tightened too much, allowing the pump to move flexibly on them. However, my old Shurflo pump became very noisy, perhaps 20 years old. I replaced it with a new Jabsco, making a huge difference to the noise. I assume that some wear in the bearings was the cause.

I used to be worried about this too - until someone posted that he saw it as a positive!
His argument was that if your freshwater system ever sprung a leak, or someone left a tap on, you would know and act long before your tanks were emptied.
It is also a great tell-tale when the young or the the vain are spending too much time in the shower
I now regard a noisy water pump as an essential feature!

Also lets you know if a tank is running dry. However, when not pumping water, the noise output is very much reduced.

Consider fitting an accumulator. It will then pump on fewer occasions, only when the accumulator needs re-filling.

Won't make it quieter though.

Make sure you only fill your tanks with soft water, it stands to reason that hard water will make more noise. Innit?
Sorry, I'm in a frisky mood today.....

Which IS when the tank is dry? (or when you have too many personal hygiene fettishists in your crew!)

Tony (if I may be so familiar) that is a very, very helpful statement, if I may say so!
Will you be in the Beer Bucket, next week? I would like to buy you a pint!

I'm a long way from the Beer Bucket (Kontokali, Corfu I assume?). But thanks for the offer.

As others have said it can be a positive thing, but if you want to take the edge of the noise, fit some insulation to the under side of the saloon seat, and to the walls of the locker.

Do check that it's mounted properly before doing anything else. Mine had part of the bracket assembled upside down so that the body of the pump as it vibrated would hammer against the plywood partition it was mounted on. That was noisy! Similarly the fridge compressor had been bolted down so tight that the rubber mounts were crushed and it was effectively rigidly mounted. It needs to be mounted without touching anything except rubber, and free to vibrate without making contact.
