FRESH WATER SYSTEM
The fresh water system provides water to the
galley sink, shower, bathroom lavatory, toilet and
water heater. Water may be supplied by either of
two sources:
•
a water tank located within the motor home, or
•
any external water source to which the motor
home may be connected, known as “city
water.”
Water Service Center
Fresh Water Tank Filling
Procedures:
Always fill the fresh water tank at an approved
potable water filling facility or a known purified
drinking water source.
The tank may be filled either by gravity fill or
by pressure filling through the city water
connection. A special diverter valve will route
the water from the hose either directly to the
water lines for city water hookup use, or to the
fresh water tank for filling.
Gravity Fill (N/A on 38J)
Insert hose into fill opening and turn water
supply on. Tank is full when water flows from
tank vent tube beneath coach.
The gravity fill tube is located behind a small,
lockable door on the left (driver) sidewall toward
the back of the coach.
Pressure Fill from City Water Connection
1. Attach hose to city water connector.
2. Open the Gravity Fill door to provide
adequate air venting and avoid pressure
buildup.
3. Turn the Fresh Water Valve inside water
service center to Tank Fill position.
4. Turn city water supply on.
5. Tank is full when water flows from tank vent
tube beneath coach.
6. Turn off city water supply and disconnect
from city water connector.
7. Turn Fresh Water Valve to Normal position to
use the water demand pump. The Tank Fill
position is only for pressure filling the water
tank from the city water hose connection.
