PLUMBING
SYSTEMS
The plumbing systems
in
your
motor
home
are
con-
structed
of
thermoplastic materials. Holding tanks and
piping components are strong, lightweight, and corro-
sion resistant.
FRESH WATER SYSTEM
Fresh water is available from either an external
"city
water"
hookup
or
on board storage.
The external system is pressurized
by
the water
system
at
an RV park or
city
water supply. When you
use this system, the onboard pump is isolated from the
city
water pressure
by
a check valve. A manual valve
also isolates the onboard fresh water storage tank. This
valve can be used
to
fill
the
tank from the
city
water
supply. More
on
that
later.
Connect the
city
water system
as
follows:
• Open
the
protective door over the
city
wa!er inlet.
• Connect one end
of
a potable water hose
to
park
or
city
water
supply. This will usually be a faucet .
or valve similar to your garden hose valve at home.
"Potable
water"
hoses
are
available at
RV
supply
stores.
• Run the
city
water supply for a
few
seconds to
clear the line. .
• Turn the supply
OFF.
•
If
a potable water hose
is
not already connected
to
the inlet, connect
the
hose to the inlet fitting.
•
Tum
the supply ON. Open
all
faucets and clear the
lines. Close faucets. If you
want
to
fill the fresh
water tanK from the
city
water supply open the
tank fill valve. Remove the water tank fill cap
to
vent the tank.
Be
careful when you do this. Monitor
the filling
of
the tank continually. The
flow
and
pressure
at
some park and
city
water supplies could
damage
the
tank
if
left unattended. Afterfilling the
tank,close
the
valve and replace the tank fill
cap.
CAUTION: OVERFIUING THE
FRESH
WATER
TANK FROM A PRESSURIZED SOURCE MAY
CAUSE SERIOUS DAMAGE
TO
THE
WATER
TANK
OR STRUCTURAL COMPONENTS. MONITOR
WATER TANK FILLING CONnNUALLY.
Disconnect
the
city
water as follows:
• Close the park or city water supply valve.
• Remove the hose from the city water supply
valve.
• Disconnect the hose from the inlet, coil & store it.
The onboard water storage tank
may"
also
be
filled
through a special filler cap outside the motor
home.
To
fill the fresh water tank, open the spout. remove vent
plug and fill the tank
with
the
hose.
After filling the tank,
close the spout, and replace the vent plug.
21
Avoid leaving water in the tank when the motor
homE
is
not
in
use.
Turn
the water pump
OFF
before draining
the water tank. Whenever possible, drain the fresh water
tank before traveling. Water in the tank
will
reduce the
carrying capacity of the motor home. See "WEIGHING
AND LOADING" section.
Exterior Shower
An exterior shower fixture is located in the water tank
compartment. The water pump
must
be
ON
or
city
water pressure
must
be available for
the
shower to
operate.
Water Purifier System
The water purifier system can help provide consis-
tent
drinking water quality
as
you travel. A special filter
is part
of
this system. The filter cartridge is located in
the cabinet under the galley sink. Your
Owner's
Infor-
mation Package contains detailed operating and
maintenance instructions concerning this system.
Please
note that the special faucet
at
the galley
is
the only outlet for the purifid water. Although purified
water is
not
available
at
the standard galley and lavy
outlets, the water available at these outlets
is
filtered
by the water pump filter.
Note also
that
this. system is
not
designed
for
or effec-
tive
In
removing
or
neutralizing bacterial contaminants.
The
Water Pump
The onboard fresh water system is pressurized
by
a
self-priming, 12-volt DC pump. The
pump
operates
automatically when the pump power
switch
is ON and
a faucet
or
valve is opened. When the faucet
or
valve
is closed, the pump shuts off. A built-in check valve
prevents
bac~
flow
and protects the
pump
and fresh
water tank from excessive
city
water system pressures
up
to
200
psi. The pump stroke will overcome air trap-
Pl1d
in the lines thus preventing air lock.
At
free flow,
the pump draws approximately 7 to 7-
Y:.
amps, and can
run dry for extended periods without damage. A 20-amp
fuse at the converter panel protects the
pump
circuit.
See
ELECTRICAL
SYSTEM.
Turn
the pump master switch (located
on
the range
hood)
ON
to pressurize the system. When a faucet is
opened after the initial filling of the
tank,the
water may
sputter for a few seconds. This is normal and is
not
cause for concern. The water
flow
will become steady
when
all
air
is
bled from the water lines.
The
Monitor
Panel
The monitor panel allows you to conveniently check
the approximate levels
in
the fresh water tank and the
holding tanks. Electrical probes installed in
