    Posted: 11 August 2014 at 12:03
In the H355 from 2012 the water pump is placed in the front sleeping cabin right next to the water tank just below the bed. As the water pump is very noisy, we wake up every time the water pump is used during the night. 

Any idea on how to minimize the noise from the water pump?

Irritating.

Move the pump to another location, in the cabin under a bench for instance. Check the rubbers where the pump is placed on., don't put extra rubbers under the pump. Change the pump type.

Put a bottle of water (We use one of those big clothes washing up liquid bottles) in the heads for people to use during the night for flushing the toilet (fewer pump strokes) and washing their hands and switch the pump off. Fill the kettle up the night before, so somebody can make you a cup of tea without waking you up first.

Anyone fitted an accumulator to reduce the pump run time?  Was it any better and worth the effort?  

Eg http://www.mailspeedmarine.com/fresh-water-systems/jabsco/accumulator-tank-8-litre6060-606309.bhtml?utm_source=google+base&utm_medium=cpc&utm_campaign=google+shopping&gclid=CjwKEAjw9qafBRCRiYrL4-fpuFkSJACvocQ1SXBYRx-jcSuAdLQW0UKXcjBPAjQ7SGg_R6VuUnoUKBoC9_Xw_wcB

This is one of those 'when-I get-around-to-it' jobs that I've meant to research and execute......but the sun keeps shining and it keeps on looking like a nice day to sail rather than do maintenance jobs :-)

I added one in my Hanse 370.
I still do not understand why Hanse does not build them as standart?
Before i placed it on my boat my waterheater 2 times leaked very much and was nearly detroyed. I had to change twice the sealing ring.
Since i added the accumulator it works perfect. The pump only starts after 30-35 sec. and not everytime.
The pressure stays the same.

But i think i only build a 2ltr version into my boat.

We often have a crew who snores terribly. We do things like chuck socks at him, flick water etc etc
When he will not stop we take it in turns to use the heads as the pump is right next to his head
Uses lots of water but shuts him up for a while

Peter-Blake,

thanks for sharing your accumulator experience.  Like you I find the lack of one surprising as they are not a huge cost and fitting would be trivial at the factory.  It's not even on an option list that I know of.  

I thought I'd need something like the 8Ltr accumulator, so happy to hear a 2Ltr one gives a good result.  It gives more options on fitting location.  On the 400 there's a large space under the holding tank where the larger accumulator can fit.  However, I would have to first cut and install a hatch next to the toilet bowl to enable workable access to that area and to get the accumulator in.  The small one would likely slide into the area near the seacocks instead and make the job a lot simpler.  

thanks

We had a really noisy pump on our 370 which was dramatically improved when we put a 2 litre accumulator in line. It only cost 35 plus a few pounds for connectors etc. There was room in the cabinet under the sink. The only difficulty was cutting into the existing piping which was completely non standard in the UK. We overcame this by using oversized flexible pie and double clamping at the connections.
It will prolong the life of your pump enormously.

You could put the tank anywhere! Also e.g. under the kitchen sink. Just disconnect the cold water pipe with standard components you can make that work easily!
