Using City Water
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.
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 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.
Disconnecting from City Water
1. Turn the city water source off.
2. Open a faucet on the coach (such as exterior
wash station) to relieve water line pressure.
3. Disconnect the hose from the city water faucet
and store hose (retract the hose into the hose
reel- if equipped). Be sure to replace the
protective cap on the hose end to avoid
entrance by debris or insects.
NOTE:Be sure 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.
Pressure Regulators
Because city water pressure varies from
location to location, we recommend obtaining an
in-line water pressure regulator to prevent
damage to any components, connections and
seals in your fresh water system.
We recommend a regulator that controls water
pressure to
50 psi
.
max
.
These devices simply connect in-line between
the supply hose and the city water input on the
coach.
Water pressure regulators are commonly
available at most RV dealerships and many large
retail discount or home supply centers.
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
