To Disconnect from the City Water
Source:
1. Turn the city water source off.
2. Open a faucet inside the vehicle to relieve line
pressure.
3. Disconnect the hose from the vehicle and
replace the cap on the city water connection.
WATER PUMP
(Located beneath bed)
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
water line 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 Water Line
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 Owner
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) counterclockwise 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
Water pump switches are located on the
systems monitor panel and in the water service
center. While the switch is in the “ON” position,
the pump will automatically supply water
pressure as it is needed. It is recommended that
the pump switch be turned off whenever you are
away from the vehicle or not using the water
system. A slow leak in a faucet could drain the
water system and discharge the coach battery.
Initial Water Line Priming
1. Make sure that all water drain valves are
closed, including water heater valve.
2. Turn water pump switch to “OFF” position.
3. Fill water tank.
