CHAP. E
E. WATER SYSTEMS
This chapter describes the hot and cold
freshwater systems of your boat, and gives
some indications on seawater systems.
E.1 FRESHWATER CIRCUIT
The freshwater system of your Grand Soleil
39 has seven tanks with a total capacity of
240 litres, located beneath the dinette seats
(two valves in the dinette bilge allow the
tank from which water is to be drawn to be
selected).
The freshwater loading inlet is located on the
port side of the deck, along the stringer.
WHEN TAKING ON WATER, CHECK
THAT THE SUPPLY HOSE DOES NOT
DELIVER TOO MUCH WATER. THIS
COULD BE EXCESSIVE FOR THE VENT
AND BE A POSSIBLE CAUSE OF
DAMAGE TO TANKS AND PIPES.
ALWAYS CHECK THE CORRECT
OPERATION OF THE PRESSURE PUMP.
A TAP LEFT OPEN OR A LOSS FROM
A PRESSURIZED CIRCUIT CAN CAUSE
FLOODING.
Beneath the first floor panel in front of the
steps leading down to the dinette there are
the valves used for suction from the tanks,
and the delivery valves to the freshwater
pressure pump and the galley pedal pump.
Leaks from the freshwater system can at worst
drain the freshwater tanks, allowing the
water to run into the bilges. The high bilge
level is not a hazard for the boat, as the total
displacement remains unchanged and it will
continue to float as normal.
WHEN LEAVING THE BOAT
UNATTENDED, THE PRESSURE PUMP
MUST BE DISCONNECTED FROM ITS
POWER SUPPLY.
Water level in the starboard tank is monitored
by a gauge on the Main Switchboard (MS)
above the chart table.
It must be remembered that when the boat
is heeled over, given the shape of the tanks,
the quantity of water that can be sucked up
from the tanks is significantly lower than the
total capacity of tanks.
The freshwater pressure pump that supplies
the cold water distribution system is located
in the engine compartment
When power is supplied to the pump it will
start and stop automatically, controlled by a
system that detects pressure in the system.
Incorrect setting of the pressure switch can
lead to a rapid succession of repeated starting
and stopping of the pump.
If the pressure pump is still powered when
the tank is empty, the pressure switch will
obviously be unable to restore pressure in
the freshwater system, and the pump will
continue to run (with the risk of damage
caused by running without water for a long
time). Pump operation must therefore be
constantly monitored.
A 25-litre water heater (powered with 230
V AC) is installed beneath the port aft guest
cabin bed, powered and protected by a
specific breaker located in a panel on the
starboard side of the afterpeak.
