I fitted a 1L accumulator tank under the front bunk right next to the pump. No new pipe was needed - just remove a short length and insert the accumulator in between.

Obviously the larger the accumulator the more water it holds before the pump cuts in. The 1L holds approx half a litre which is sufficient to rinse your hands etc. 

As others have said, an accumulator significantly smooths out the pump cut-in/cut-out times and also avoids the hot water pressure relief valve letting water into the bilge. 

If the accumulator has a diaphragm, access to the top of the accumulator is required as you (may) need to periodically pump up the air side with a bicycle pump - maybe once a year. You can check when this is needed by the amount of water that the accumulator is holding. Some accumulators do not have a diaphragm but these lose pressure over time as the air is slowly absorbed into the water and have to be drained down to refill with air.

I placed the 2 ltr version of the accumulator right beside the seacocks underneath the washbasin.
I just took the hose of the nearby pump, added a Y-Connector and 1m of new hose. The accumalator is just fixed with some
cable ties invisible to the scews of the translucend showerwall. No extra drilling needed!

I bought this one:

I mounted an accumulator in my previous boat. Don't think it was much of use. Probably it got filled with water somehow.
During a winter it cracked by frost and I got water in the boat.

Never ever accumulator for me ...

Sure, it absolute important that the water which enters the accumulator can run out of it in winterisation. Thats why i mounted mine vertically and mine has inside a Integrated rubber membrane which can be filled with air. The cheap ones do not have something like it. So make sure you buy the correct one!

Thanks for sharing your experience. The accumulator solution sounds like a cheap and workable solution. What brand/model accumulator did you buy if I may ask?

This is the one that I used but I bought it via eBay for less than 40 if I remember correctly.


Shurflo also do a similar item.

I also have one with membran. Mine is about 8 liter, but I cant remember the brand....
I bought it from a plumber and it works perfect!
