Find the source of the noise when the pressure pump goes and the valves are likely to be close by. Usually under a dinette seat and as on off valves for each tank rather than a changeover.

First link here gives you a PDF of the owners manual. https://www.google.co.uk/search?q=s...firefox-b&gfe_rd=cr&ei=tmdzWfG2F7Ck8wf2nqHwAg

The valves you want are under the aft end of the starboard seating in the saloon.

Got it thanks. Do you know the respective water capacities of each tank?

 

[Norman_E]

Sorry, no but the manual gives a total of 355 litres, with a warning not to fill the tanks completely, which is a bit silly because you generally have no means of measuring how much is coming out of a hosepipe, On my larger Jeanneau I just fill the tanks till water overflows, then use a bit fairly quickly so that the filler hoses are emptied. My own manual says I have two 250 litre tanks but the tanks are marked 300 litres!

135 litres each. Don't rely on the LCD guage- it over reads grossly. There is also acommon issue with the pre-pump filter cover (clear plastic) cracking and preventing the pump from priming. There will be drops on the plywood beneath the pump if this is the case.

Edit: Whoops, total is 355, Rusty memory. Pretty sure tanks have equal capacity. Manual is here:

Simple filling proceedure. Fill each tank until water overflows. Fill galley sink, and let water drain, change over the tank valves and repeat proceedure. Tanks are now full but not over filled.

Forward tank 200l. Aft 135- same as fuel tank.
