5. Turn OFF city water supply and disconnect
from City Water Connection.

Using City Water
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.
1. Connect hose to City Water Connection as
described in previous steps.
2. Turn Fresh Water valve to Normal position
and turn the water pump switch(es) OFF.

(Located in water service center)
NOTE: Always keep the tank fill valve in Normal
position unless you are filling the tank. If
this valve is left in the Tank Fill position
while using the city water, water will
keep flowing into the tank and out the
7-2
tank vent tube onto the ground and the
water pump will run without delivering
water to faucets.
Disconnecting from City Water
1. Turn the city water source OFF.
2. Open a faucet on the coach (such as the
exterior wash station, if equipped) to relieve
line pressure.
3. Disconnect the city water hose from the coach
and replace the cap on the Fresh Water Inlet.
NOTE: Ensure the Fresh Water valve is in
NORMAL position to use the water
pump. If the valve is in Tank Fill position,
the pump will run continuously without
delivering water.

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
