The water pump should be turned off when using city wa-
ter. City water pressure varies from area to area. If the
pump is ON and water pressure drops below 35 p.s.i., the
pump will activate to maintain pressure at 35 p.s.i. It will
draw water out of tank and bypass city water.
If the pump is OFF, the pump will not function and the
water in the storage tank of the boat will not be utilized.
Always remember to disconnect the shore water
supply hose before leaving the dock.
Always turn off the shore water whenever the boat
is left unattended. If a major water leak did occur
and went undetected, the boat could fill with wa-
ter and sink.
DO NOT alter or repair the pressurized water sys-
tem or shore water connection without having
proper knowledge of the system. Damage to the
water system can occur.
See Section J-1 for general water system information and
instructions on filling the water tank. The water tank will
not be filled while connected to shore water.
The transom shower is standard on the Four Winns 348
Vista model. The shower unit is usually located on the
starboard side of the transom near the boarding ladder
grab rail. Refer to Figure J2 and to the drawings at the
end of this section.
The water supply system can be used for showering or
washing down the transom. As long as there is water
pressure, the shower faucet will operate.
Fresh water tank capacity is limited. Connect the boat to
shore water before using large amounts of water as re-
quired when washing down the boat.
The various antipollution laws presently in effect have
necessitated the use and availability of a wide variety of
heads. The heads that have been factory installed in
Four Winns® boats have been chosen to provide reason-
able longevity and reliable service, at a realistic cost.

Refer to the drawings at the end of this section. Also,
refer to the manufacturers literature included in the
owner’s packet.
The 348 has the VacuFlush sanitation system as a stan-
dard feature. The system eliminates the unpleasant
sulfide odors which plague saltwater systems. Flush
water is no longer drawn through the through hull fit-
tings, seacock and vented loop. It also extends the life
of the system components by eliminating salt water
and impurities from accumulating in the system over
time.
The VacuFlush toilet operates in a different way from
other marine toilets. VacuFlush systems use a small
amount of water (a little more than a pint) per flush in
addition to a simple vacuum. The toilet is connected to
a fresh water system. Fresh water is the key to an
odor free bathroom compartment. VacuFlush toilets
are equipped with an intergrade vacuum breaker which
prevents the possible contamination of the potable/fresh
water supply. See Figures J4 & J5 and refer to the
drawings at the end of this section. Also, refer to the
manufacturers literature included in the owner’s packet.
