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 behind the service center. The pump
may be accessed from the storage bay next to
the service center.
Water pump inlet screen: Located
behind plumbing manifold. Clean
every two months.
WARNING:
Before leaving the motorhome for
extended periods of time (i.e. overnight
or longer) be sure that the city water
supply and water pump have been
turned off. Damage from neglect will be
the responsibility of the owner, not the
manufacturer.
The water pump can be
operated from these following
locations:
Bathroom/Vanity
Galley
Service Center
To turn the water pump
ON or OFF:
Momentarily press the
water pump switch. The
indicator lamp on the
interior switch or the LED
on the service center switch
will illuminate when the
water pump is turned on.
CAUTION:
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.

Water Pump Troubleshooting

Vibration induced by road conditions can
cause the plumbing or pump hardware to
loosen. Check the water pump system for
components that are loose. Many symptoms
can be resolved by tightening the hardware.
Water pump will not start or blows 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 system for correct
voltage and good ground.
Check for an open or grounded circuit
or motor.
Check for a seized or locked diaphragm
assembly (water frozen).
