V. DRAIN and SANITATION SYSTEM
Drainage system characteristics (ISO 15083:2003)
Read the operating and maintenance instructions for your boat’s bilge pump carefully.
WARNING
The bilge pump system is not designed to handle water entering as a result of holing of
the hull. It is intended to remove water coming from spray, leaks from seacocks or other
moderate leaks.
ATTENTION!
● The level of water in the bilge must be kept to a minimum.
● Make sure that bilge pumps are in working order before putting to sea.
● Regularly remove any debris that might obstruct the sump well and the pump intake
points or strainers.
If the watertight bulkheads that isolate the fore- and after-peaks are fitted with valves, they
should normally be kept closed and should only be opened to drain the water into the main
bilge.
● Know where to find each hand pump and its handle.
● Locate the switch for the electric bilge pump on the electrical panel.
Pressurized freshwater pump
Freshwater is supplied to the sink and washbasins by an electric pump. A filter is installed
upstream of the pump, and must be cleaned regularly.
Never allow the pump to run if the tank is empty. Refill the tank before using the water
supply again.
The tanks can be sterilized using Clonazone® tablets (available from pharmacies). Every
year, remove the inspection covers and clean them by filling with water containing a
bactericidal detergent; leave it to act for a few hours, then rinse two or three times. During
wintering, completely fill the tanks to avoid the development of algae or bacteria. If there is a
risk of freezing, empty the tanks; never use anti-freeze.
Hot water is produced by a water-heater connected to the engine cooling circuit and the shore
electric supply.
After the water-heater has been emptied, make sure that the element is covered before power
is re-applied.
