WATER
PUMP TROUBLESHOOTING
The
water
pump in your system is a durable device
that
will
operate for years
with
little
attention.
Most
water
pump
problems can
be
solved
by
a
common-
sense approach. The
following
is a discussion
of
possible trouble spots and
what
to
do.
Pump
Motor
Does
Not
Operate
•
Be
sure "Water Pump" master switch is on. Even
though
the
pump
operates
automatically
when
a faucet is opened,
the
pump
master
switch
has
to
be
on
for
that
to
happen.
• Check
battery
condition.
If
the
battery
is
discharged,
the
pump
won't
run.
• Check
the
fuse. The
water
pump fuse is located
on the electrical distribution panel.
If
it
is blown,
there is a reason
for
it. Check the pump
wiring
for
shorts. Do
not
replace
the
pump fuse
with
a fuse rated more than 10-amps.
• Check
for
disconnected or corroded wires or
terminals.
Clean and reconnect
if
necessary.
• In cold weather, check
for
pump
freeze up.
If
water
is frozen in
the
pump
head,
thaw
it
by
placing a light bulb near
the
pump head.
DO
NOT
USE
A TORCH
OR
OTHER
OPEN
FLAME.
Pump
Motor
Runs
But
No
Water
Flows
•
Be
sure there is
water
in
the
fresh
water
tank.
Check level
at
the
monitor
panel.
See
MONITOR
PANEL section.
• Check
the
filter.
If
it
is clogged, remove
it
and
try
backflushing
it
as a temporary fix.
If
that
doesn't work,
it
must
be replaced.
• Check inlet and
outlet
hoses and fittings. Look
for
kinked
or
collapsed hoses, or loose clamps
that
could be
letting
air
into
the
system. Avoid
storing anything in the water pump area. A heavy
item could
flatten
a hose or damage
the
inlet
or
outlet
hoses and
fittings.
Pump
Runs
But
Water
Sputters
• This is normal after
an
initial filling of the
tank
and lines.
It
should stop in a
few
seconds.
•
If
sputtering
continues,
the
water
tank
may
be
almost
empty. Add
water
if
necessary.
•
If
sputtering continues, check for air leaks in the
inlet side
of
the pump.
Pump
Cycles
On
And
Off
When
All
Faucets
Are
Closed
• Check
for
leaks in the
water
lines.
22
•
Be
sure
tank
drain valves are
tightly
closed.
• The pump may have
an
internal leak. Refer pump
repairs
to
an authorized
Fleetwood
RV
Service
Center.
Pump
Does
Not
Shut
Off
• Water
tank
may
be
empty.
• Check battery condition. A
low
battery
will
allow
the pump
to
run
but
not
develop enough pressure
to
shut
off.
• The
pump
switch
mechanism
may be stuck.
Gently
tap
the
switch
cap
on
the end
of
the
pump
with
a screwdriver handle.
•
If
the
switch
mechanism needs replacing, refer
repairs
to
an
authorized Fleetwood
RV
Service
Center.
Pump
Head
Leaks
• Tighten screws in pump head assembly.
DO
NOT
OVERTIGHTEN.
• The head may be cracked. This can be caused
by stress failure,
but
is more likely caused by
water
freezing in
the
pump
head. Refer repairs
to
an authorized
Fleetwood
RV
Service Center.
Pump
Does
Not
Prime
• Water
tank
may
be
empty.
• Filter may
be
clogged.
• Inlet hoses
may
be
kinked or collapsed.
• Failure
to
prime is usually caused by internal
pump
valve failure
or
foreign material lodged in
a valve seat. These
conditions
require
pump
disassembly. Refer these repairs to an authorized
Fleetwood
RV
Service Center.
THE WASTE WATER SYSTEM
The waste water system in your
motor
home is
made up
of
sinks, tub, shower, toilet,
plumbing
drain
lines, a
"gray
water"
holding
tank
that
accumulates
waste
water
from sinks and
tub
only, and a
"black
water"
holding tank
that
holds toilet wastes only. The
holding tanks make
the
system
completely
self-
contained and allow you
to
dispose
of
waste
water
at your convenience. A flexible sewer hose is required
to
connect
the
holding
tank
outlets
to
the
inlet
of
an
approved waste water dump station
or
sewer system.
The drain plumbing is very similar to
that
used in
your home. The system is trapped and vented
to
prevent waste gases from backing
up
in
to
the
motor
home. The drain plumbing is made
of
ABS plastic, and
is durable, and resistant
to
most
chemicals. All drain
plumbing except the
toilet
connection
terminates in
