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
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.
NOTE: Always leave gravity fill door OPEN
while filling tank.
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 water pump and storage
tank and supplies pressure directly to individual
faucets and toilet. A check valve built into the
water pump prevents water from entering the
pump and filling the storage tank.
Connecting City Water Source:
1. Turn the Water Pump switch OFF.
2. Attach an RV city water hose from the
external water source to the city water
connection (typically located in the water
service center or on the left sidewall of your
vehicle).
3. Turn on the external water source.
