5.1 Fresh Water System
General
The fresh water system consists of a potable
water tank, distribution lines and a distribu-
tion pump. The pump comes with an auto-
matic pressure switch and is located in the
stern bilge. An in-line strainer located near
the pump protects the system from debris. A
labeled deck plate located on the gunwale
allows for filling the tank.
Operation
Fill the water supply tank slowly through the
labeled deck plate. After filling the water
tank, partially open all faucets. The fresh
water system switch on the helm panel
should be "ON." Allow the pump to run until
purging all the air from the system and a
steady stream of water flows from each out-
let. Next, turn off the faucets one by one. As
the pressure builds, the pump will automati-
cally shut off.
After properly priming and activation, the
water system will operate much like the
water system in a home. An automatic pres-
sure sensor keeps the system pressurized.
Recently filled tanks or tanks used for an
extended period may cause air accumula-
tion at the pump and the system may need
to be re-primed.
Whenever unattended, place the fresh water
system switch in the “Off” position.
Sink and Shower Operation
To use the galley sink, head sink or shower,
turn on the fresh water system. The head
sink faucet is also the shower spray head.
To use, lift the spray head off the sink and
turn the water on. Some minor variations in
the water temperature and pressure may
occur as the pump cycles. The sinks drain
overboard.
Water drains from the shower to a sump
pump system located in the bilge below the
cabin floor. An automatic float switch in the
shower sump controls the pump. After show-
ering, let the cold-water flow for a while to
flush the drainage system of soap residue. It
is essential to clean the shower drain
strainer regularly. Periodically inspect and
remove accumulated debris from the sump.
Water Heater
The water heater is located in the machinery
space. All heaters have a thermostatically
controlled AC element at the heater, acti-
vated by a circuit breaker located in the AC
panel. A high-pressure relief valve protects
the system from excessive pressure. Purge

CAUTION
Do not fill the system with anything
other than water. Contamination of the
system with fuel or other toxic fluids
may necessitate the replacement of
components.
!
WARNING
Do not confuse fuel-fill deck plates
with the water or waste-fill deck
plates. If gasoline or diesel acciden-
tally is pumped into the water or waste
tank, do not attempt to pump it out
yourself. Water and waste pumps can
cause a fire or explosion. Have the
fuels professionally removed and the
components of the fresh water system
replaced as necessary.
!
CAUTION
Do not allow the fresh water pump to
run dry. Empty fresh water tanks will
cause the pump to stay on as the
pump works on-demand and will not
shut off automatically. This can result
in damage to the pump. Always turn
the water pressure switch "Off" when
not in use.
