V. DRAIN & SANITATION SYSTEM
Characteristics of the drain system (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.
CAUTION!
● The level of water in the bilges must be kept to a minimum
● Make sure that bilge pumps are in working order before putting to sea.
● Regularly clean the bilge and pump suction points or strainers to keep them free of any debris
that could obstruct them.
If the watertight bulkheads
isolating the forepeak and afterpeak are fitted with valves, these
should be kept closed and only opened to drain water in 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 fresh-water pump
Fresh water 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.
