PLUMBING SYSTEMS
5.1 Fresh Water System
GENERAL
The fresh water system consists of a potable water tank, distribution lines and a distribution pump. The pump
is equipped with an automatic pressure switch and is located in the machinery space. An in-line strainer located
near the pump protects the system from debris. The tank is filled through a labeled deck plate located on the
gunwale.
DO NOT FILL THE SYSTEM WITH ANYTHING OTHER THAN WATER. SHOULD THE
SYSTEM BECOME CONTAMINATED WITH FUEL OR OTHER TOXIC FLUIDS, COMPO-
NENT REPLACEMENT MAY BE NECESSARY.
DO NOT CONFUSE FUEL FILL DECK PLATES WITH THE WATER OR WASTE FILL
DECK PLATES. THESE PLATES ARE ALSO LABELED ACCORDINGLY. IF GASOLINE
OR DIESEL IS ACCIDENTALLY PUMPED INTO THE WATER OR WASTE TANK, DO NOT
ATTEMPT TO PUMP IT OUT YOURSELF. WATER AND WASTE PUMPS ARE NOT DE-
SIGNED TO PUMP FUEL AND A FIRE OR EXPLOSION COULD RESULT. HAVE THE FUEL
PROFESSIONALLY REMOVED AND THE COMPONENTS OF THE FRESH WATER SYSTEM
REPLACED AS NECESSARY.
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 located on the helm panel should be on. 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 much like the water system in a home.
An automatic pressure sensor keeps the system pressurized. If the system has been recently filled or has not
been used for an extended period, air bubbles may accumulate at the pump and the system may have to be
reprimed. Whenever the boat is left unattended, the fresh water system switch should be placed in the “OFF”
position.
DO NOT ALLOW THE FRESH WATER PUMP TO RUN DRY. THE FRESH WATER PUMP
WORKS ON DEMAND AND WILL NOT SHUT OFF AUTOMATICALLY WHEN THE TANK
IS EMPTY. THIS CAN RESULT IN DAMAGE TO THE PUMP. ALWAYS TURN THE WA-
TER PRESSURE SWITCH OFF WHEN THE FRESH WATER SYSTEM IS NOT IN USE.
WATER HEATER
The water heater is accessed through the machinery space. All heaters have an AC element that is
thermostatically controlled at the heater and activated by a circuit breaker on the AC breaker panel. A high
pressure relief valve protects the system from excessive pressure. Always make sure all air is purged from
the water heater and lines before activating the water heater breaker. Refer to the water heater owner’s manual
for additional information.
