WATER AND WASTE SYSTEMS

J - 1

GENERAL

All Four Winns Vista™ models are equipped with a fresh
water supply system. This system consists of a water
supply tank, water distribution lines and a distribution
pump. The water fill deck plate for the fresh water sys-
tem is located on the forward port deck. Always fill the
tank slowly.
The water deck plate is appropriately labeled.
DO NOT fill the system with anything other than
water. Should the system become contaminated
with fuel or other toxic solution, component re-
placement may be necessary.
The water tank is equipped with an overboard vent. Main-
tain a close visual watch on the overboard vent while fill-
ing the water tank. Always fill the tank slowly. When the
tank is almost full, water will spurt out of the vent.
NOTICE
When filling the tank, never seal the hose to the
deck plate. The tank will become pressurized
and could rupture.
The capacity of the fresh water tank for the 378 Vista™
is 66 gallons/249 liters. This model comes standard
with tank monitoring system, located in the head, to
check water/waste level. The tank location is in the
floor of the main cabin. Access to the tank is gained
through an access in the cabin floor. See Figure J1.

The materials from which the components of the water
system are made may give the water supply a peculiar
taste, especially when new. This condition is normal and
can be reduced somewhat through the use of a water
filter; such as that produced by PuriTec™ and Aqua-
bon™. The taste will completely dissipate in time.
The fresh (potable) water system should be dis-
infected prior to initial use.
The water system should be disinfected before first use
and at the beginning of each season. The following infor-
mation is a general guide to disinfecting the fresh water
system.
1. Flush the boat's water system thoroughly with fresh
water. Make sure all nontoxic antifreeze is removed
from the system.
2. The water system should be drained completely.
3. To disinfect the water system, use one gallon of wa-
ter and 1/4 cup of Clorox™ or Purex™ household
bleach (5% sodium hypochlorite solution). This is
recommended for each 15 gallons of tank capacity.
4. Allow to stand for three (3) hours. If time is a factor,
greater concentrations of chlorine solution will be
needed to disinfect the water system.
5. Drain the system.
6. Flush the system thoroughly with fresh water.
