5.1 Bilge pump system
A main sump is under the floorboard of each hull.
The fore and aft compartments are linked to these sumps by a bilge
pipe and a valve (access under the floorboards).
Each fore compartment is drained by a manual pump.
Each sump is drained by :
- A cockpit manual pump.
- An electric pump with a manual or automatic start (on the electrical
panel).
An automatic start for a low level starts the pump but not the alarm
(draining of the bilge pipes).
An automatic start for a higher level starts the alarm then.
Nota : the electric bilge pump automatically works even if the 24 V
system has been switched off.
Each of the engine bilges has an electric pump with a manual or
automatic start.
„
5.2 Grey water system
The grey waters are grouped together in a collecting tank in each hull.
They collect the waste waters of the basins and showers of the
shower rooms.
The grey water tanks are emptied by automatic start pumps
(switching on from the 24 V panel).
We advise you should regularly clean the filters (access to them by
removing the clips of the covers).
