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 motorhome,
or
•
Any external fresh water source to which the
motorhome may be connected, known as “city
water”.
Water 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.
These devices simply connect in-line between
the supply hose and the city water input on the
coach. We recommend regulators that control
water pressure to
50 psi. max
.
Water pressure regulators are commonly
available at most RV dealerships and many large
retail discount or home supply centers.
Filling the Fresh Water Tank
Through Gravity Fill
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 driver sidewall.
•
Insert hose into fill opening and turn water
supply on. Tank is full when water flows from
the tank vent tube beneath coach and out of the
Gravity Fill door.
Using Tank Water (Gravity Fill)
•
Turn Water Pump switch ON. While the
switch is on, the water pump will
automatically supply tank water as needed.
WATER PUMP
When your coach is not connected to a city
water supply, water is supplied from the fresh
water tank by a water system demand pump. A
demand pump is designed to run only when you
are using water. When you open a faucet, the
waterline pressure drops and the pump begins to
run, and it will continue to run as long as the
faucet is open. When you close the faucet, the
line pressure backs up to the pump, and it shuts
itself off.
The pump is self-priming and will run briefly
to build up line pressure when the Water Pump
switch is first turned on. See “Initial Waterline
Priming” for instructions on using the water
system for the first time.
WARNING
Potable water only.
Sanitize, flush, and drain water tank
before using.
See owner’s manual for instructions,
care, and maintenance information.
Failure to maintain tank can result in
death or serious injury.
