5.1 Fresh Water System
General
The fresh water system consists of potable
water storage, distribution lines and a distri-
bution pump. The pump is equipped with an
automatic pressure switch and is accessed
through the center in-deck floor hatch. An in-
line strainer located near the pump protects
the system from debris. The tank is filled
through a labeled deck fill located under the
center in-deck floor hatch.
DO NOT confuse other deck fills with the
fresh water fill. If toxic fluids are added to
fresh water tank, the system will be contami-
nated. If this happens then the tanks and
entire fresh water system must be repaired
by qualified personal only. It may also
require replacement of that system and/or
many components.
Operation
Fill the water supply tank slowly through the
FRESH WATER FILL. After filling tank, par-
tially open all faucets. Turn on the “Fresh
Water System” switch at the helm. Allow the
pump to run until all of the air is purged from
the system and a steady stream of water is
flowing from each outlet. Next, turn off the
faucets one by one. As the pressure builds,
the pump will automatically shut off.
When properly primed and activated, the
water system will operate like the water sys-
tem in a home. An automatic pressure sen-
sor keeps the system pressurized. If the
system has been recently filled or has not
been used for an extended period, air may
accumulate at the pump and the system
may have to be re-primed.
Whenever the boat is left unattended, turn
the fresh water system switch "OFF."
Sink and Shower Operation
The head sink faucet is also the shower
spray head. To use as a shower, turn on
“Fresh Water System” switch on the MDP, lift
the spray head off the sink (or out of the
receiver for the cockpit shower) and turn the
water on. Adjust the hot and cold water fau-
cet until the desired temperature is obtained.
Some minor variations in the water tempera-
ture may occur as the pressure pump
cycles.
Shower and sink water is drained from the
head compartment by a sump pump system
connected to the shower drain. An automatic
float switch in the shower sump controls the
pump. The pump is protected by the shower
sump circuit breaker. After showering, let the
cold water flow for a period of time to flush
the drainage system of soap residue.
The shower sump system is located in the
bilge, below the forward in-deck hatch. It is
important the shower drain strainer is
cleaned regularly and the sump is inspected
regularly to remove any accumulated debris.
Water Heater
The water heater is located below the center
in-deck hatch. All heaters have an AC ele-
ment that is thermostatically controlled at the
heater and activated by a circuit breaker
located in the AC panel. A high pressure
relief valve protects the system from exces-
NOTICE
DO NOT allow the fresh water pump to
run dry; damage to the pump can
occur. The fresh water pump works on
demand and WILL NOT shut off when
the tank is empty. Turn the water
pump switch "OFF" when the system
is not in use. Operating any pump
from a low-charged battery can lead
to a pump failure. Keep the batteries
properly charged. The fresh water
system must be properly winterized
prior to winter lay-up. Refer to
Winterizing.
