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 gravity tank fill tube is located behind a
small, lockable door on the left (driver) sidewall
toward the back of the coach.
Insert hose into fill opening and turn water
supply on. Tank is full when water flows from
tank vent tube beneath coach.
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.
Connecting City Water Source:
1. Turn the demand pump switch to off.
2. Attach an RV city water hose from the
external water source to the city water
connection typically located in the water
service compartment or on the left sidewall of
your vehicle.
3. Turn on the external water source.
NOTE: Always keep the tank fill valve in Normal
position unless you are filling the tank. If
this valve is left in the Tank Fill position
while using the city water, water will
keep flowing into the tank and out the
tank vent tube onto the ground and the
water pump will run without delivering
water to faucets.
Disconnecting from City Water
1. Turn the city water source off.
2. Open a faucet on the coach (such as the
exterior wash station if equipped) to relieve
line pressure.
3. Disconnect the city water hose from the coach
and replace the cap on the fresh water inlet.
Pressure Regulators
Because city water pressure varies from
location to location, we recommend obtaining an
in-line water pressure regulator to prevent
damage to any components, connections and
seals in your fresh water system.
We recommend a regulator that controls water
pressure to
50 psi
.
max
.
These devices simply connect in-line between
the supply hose and the city water input on the
coach.
