Connecting City Water Supply
When connected to an outside source of water,
the water bypasses the water pump and storage
tank and supplies pressure directly to individual
faucets and toilet. A check valve built into the
pump prevents water from entering the pump and
filling the storage tank.
•
Connect hose to City Fill Inlet.
Disconnecting from City Water
•
Turn the city water supply OFF.
•
Open a faucet on the motorhome (such as the
galley faucet) to relieve line pressure.
•
Disconnect hose from the motorhome and
replace cap on the City Fill Inlet.
WATER PUMP
When your motorhome 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.
Water 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 if using the blowout
winterization procedure.
To Clean Pump Strainer
•
Ensure 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.
