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 by hose, known as
"city water".

Fresh Water Tank Capacity:

Models 34Y, 35U & 36W ........................ 80 gal.
Model 36L (diesel) .................................... 86 gal.
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.
You can fill your water tank using either of
two methods; gravity fill or city water pressure
fill.
Gravity Fill: Insert hose into fill opening and
turn water supply on. Tank is full when water
flows from overflow tube beneath coach. The
gravity fill tube is located behind a small, lock-
able door on the right (passenger) sidewall to-
ward the back of the coach.

PLUMBING SYSTEMS
NOTE: Model 34Y does not have a gravity fill
tank on the exterior sidewall of the
coach. An auxiliary tank fill hole is pro-
vided on the top of the water tank. The
large fill plug may be removed with a
wrench to add RV water line antifreeze
or to fill the tank if city water pressure is
not available.
To Pressure Fill Water Tank from City Water
Connection:
1. Attach a hose from a city water faucet to the
city water connector in the water center on
the left (driver) side of your coach.
2. Turn the water center diverter valve to the
WATER TANK FILL position as shown in
following photo.
3. Open city water faucet. (See subsequent
NOTE for pressure regulator recommenda-
tion.)
4. Tank is full when water begins to flow from
the tank vent tube beneath the coach.
NOTE: Because city water pressure varies from
location to location, we recommend us-
ing an in-line water pressure regulator
to prevent damage to any components,
connections and seals in your fresh wa-
ter system.
A water pressure regulator may be ob-
tained from any well stocked RV dealer-
ship retail center and some retail
discount centers. These devices simply
connect in-line between the supply hose
and the city water input on the coach.
We recommend a regulator that controls
water pressure to 40 psi maximum.
NOTE: Be sure to open the gravity fill door to
prevent pressure build up while filling
the tank from the city water connector.
