10 - PLUMBING SYSTEMS
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, known as “city
water”.
Fresh Water Tank Filling Procedures
Always fill the fresh water tank at an approved
potable water filling facility or a known purified
drinking water source.
The tank may be filled either by gravity fill or
by pressure filling through the city water connec-
tion. A special diverter valve will route the water
from the hose either directly to the water lines for
city water hookup use, or to the fresh water tank
for filling.
Gravity Fill
Insert hose into fill opening and turn water
supply on. Tank is full when water flows from
tank vent tube beneath coach. The gravity fill
tube is located behind a small, lockable door.

WAT ER PUMP
(Located beneath bed)
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. This is what happens when you
turn a faucet on - the water line pressure drops
and the pump begins to run, and it will continue
to run as long as the faucet is open. When you
turn the faucet off, 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 Water Line
Priming” for instructions on using the water sys-
tem for the first time.
Pump Strainer Filter
The pump is equipped with a cleanable strain-
er filter to capture any possible tank borne parti-
cles that could damage pump components.
Note: We recommend that you check and clean
this filter after each tankful of water dur-
ing the first few uses of the water pump
system. Thereafter, remember to check it
at least yearly, such as during winteriza-
tion procedures.
To Clean Pump Strainer
Be sure all water pump switches are OFF.
• Twist the inlet cap (bowl) counterclockwise
to unscrew from the filter assembly.
