WATER PUMP

The water pump pressurizes
the fresh water system when
not connected to city water. The
water pump is self-priming,
operating on demand as water is
used. The water pump is located
in the water service center.
To Operate the Water Pump:
Ensure the house battery
‹
disconnect switch is on.
Battery cut-off switch must
‹
be on.
WARNING:
Before leaving the
motorhome for extended
periods of time (i.e.
overnight or longer) the
city water source and water
pump must be turned off.
The manufacturer is not
responsible for damage
caused from neglect.
Water Pump Switches are
Located:
The galley
‹
Bathroom.
‹
Water service center.
To Turn the Water Pump
On or Off:
Momentarily
‹
press the water
pump switch. The
indicator lamp

illuminates when
the water pump is
turned on.
WARNING:
Do not continue water
pump operation if the
fresh water holding tank is
empty. Damage to the water
pump or electrical supply
system may result.
To operate the water pump
after unhooking from city
water or removal from
storage:
Close all drain valves and
‹
low point drains.
Fill the fresh water tank.
‹
Turn on the water pump.
‹
Individually open each
‹
faucet, hot and cold valves
until each faucet delivers a
steady stream of water.

Water Pump Troubleshooting

Vibration, induced by road
conditions, can cause the plumbing
fittings and/or pump hardware to
loosen. Check the water pump
system for components that may
have been jarred loose especially
after removal from storage as
freeze damage may have occurred.

Water pump will not start or
blows the fuse:
Check the electrical
‹
connections, fuse or
breaker, main switch and
ground connection.
Is voltage present at
‹
the pressure switch on
the pump? If voltage is
present, the pressure switch
may be faulty. As a test,
temporarily bypass the
pressure switch.
Check the charging
040537c
‹
Typical water pump system for correct voltage
switch
and good ground.
Check for an open or
‹
grounded circuit or motor.
Check for a seized
‹
or locked diaphragm
assembly (water frozen).
Water pump will not prime or
sputters (No discharge/motor
runs):
Check the pump inlet
‹
strainer for clogs and
debris.
Check the
‹
tank for
water or air
collected in
the water
heater.
Check
‹
the inlet
tubing and
plumbing to
see if it is
sucking in air
at plumbing connections
(vacuum leak).
Check for proper voltage
‹
with the pump operating.
Check the pump housing
‹
for cracks or loose drive
assembly screws.
