Plumbing Systems
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
all the air is purged 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.
5.2 Raw Water Washdown
Hoses connected to a ball valve and thru-
hull fitting located in the bilge supply the raw
water washdown pump.
Operation
Always make sure the ball valve is open
before attempting to operate the raw water
washdown system. A switch on the helm
activates the washdown pump. When acti-
vated, the pressure switch will automatically
control the pump. As the pressure builds in
the washdown hose, the pump will shut off.
When the washdown hose is in use and the
pressure drops, the pump will turn on. Turn
off the washdown system off when not in
use.
The raw water washdown system is
equipped with a sea strainer on the intake
side of the pump located in the aft bilge.
Check the strainer frequently and clean as
necessary.
!
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.
