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 fresh water tank and water pump located
within the motor home; or
•
any external fresh water source to which the
motor home may be connected, known as
“city water.”
Filling the Fresh Water Tank
Always fill the fresh water tank at an approved
potable water filling facility or a known purified
drinking water source.
The tank is filled through the city water
connection (Fresh Water Inlet) inside the water
service center.
The Fresh Water Valve routes the water from
the city water hose to the fresh water tank for
filling.
1. Attach hose to the Fresh Water inlet.
2. Turn the Fresh Water Valve to Tank Fill
position.
3. Turn city water supply on.
4. Tank is full when water flows from tank vent
tube beneath coach.
5. Turn off city water supply and disconnect
from city water connector.
6. Turn Fresh Water Valve to Normal position to
use the water pump.
The Tank Fill position is
only for pressure filling the water tank from
the city water hose connection.
Using City Water
When connected to an outside source of water,
the water bypasses the demand pump and storage
tank and supplies pressure directly to individual
faucets and toilet. A check valve built into the
pump prevents water from entering the pump and
filling the storage tank.
1. Connect hose to city water connection as
described in previous steps.
