WATER PUMP

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. When you open a faucet, the
waterline pressure drops and the pump begins to
run, and it will continue to run as long as the
faucet is open. When you close the faucet, 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 Waterline
Priming" for instructions on using the water
system for the first time.
Further Information
See the water pump manufacturer's operation,
care, and maintenance information in your
InfoCase.
Pump Strainer
The pump is equipped with a cleanable
strainer to capture any possible tank-borne
particles that could damage pump components.
NOTE: We recommend that you check and clean
the strainer after each tankful of water
during the first few uses of the water
pump system. Thereafter, remember to
check it at least yearly, and be sure to
empty water from it during winterization
procedures.

To Clean Pump Strainer
• Be sure all water pump switches are OFF.
• Twist the inlet cap (bowl) counter-clockwise
to unscrew from the strainer assembly.
• Remove the bowl and pull the strainer screen
out of the bowl to tap out any particles and
rinse clean.
• Insert the strainer screen back into the bowl,
then screw the bowl back onto the strainer
assembly.
NOTE: You must also empty the strainer when
winterizing your coach to avoid water
freezing and cracking the filter bowl.
Water Pump Switch
The water pump switch is located near the
monitor panel (some models may have an
additional switch in the water service center or
within the bathroom area for your convenience).
While the switch is "ON", the pump will
automatically supply water as it is needed.
We recommend that you turn the water pump
switch off whenever you will be away from the
vehicle or not using the water system. In time, a
slow leak in a faucet could drain the water tank,
fill the holding tank, and discharge the house
batteries.
