City Water Use
Connect hose to city water connection as
described in previous steps. Turn Fresh Water
Valve to Normal position and turn demand water
pump switches OFF.
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
tank vent tube onto the ground and the
water pump will run without delivering
water to faucets.
When connected to an outside source of water,
the water bypasses the demand 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.
NOTE: Because city water pressure varies from
location to location, we recommend
using an in-line water pressure
regulator to prevent damage to any
components, connections and seals in
your fresh water system.
A water pressure regulator may be
obtained from any well stocked RV
dealership retail center and some retail
discount centers. These devices simply
connect in-line between the supply hose
and the city water input on the coach. We
recommend a regulator that controls
water pressure to 40 psi maximum.
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.
Disconnect the hose from the vehicle and
replace the cap on the city water connection.
UTILITY LIGHT
A lamp is located up on the left sidewall to
provide light in the water service center.
The switch is located inside the water service
center compartment on the left side of the coach.
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
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.
