FRESH WATER SYSTEM
Your Trailer is outfitted with a system designed to
provide fresh (potable) water service from an on-
board water tank or a city water connection with a
fresh water tank fill located on the roadside of the
trailer.
When connecting to the city water hookup, use only
a non-toxic water hose, available at most RV supply
stores. Since water pressures at campgrounds and
household hookups vary, you should install an inline
pressure regulator at the water supply faucet. This will
protect both the trailer water system and supply hose
from excessively high water pressure.
WATER PUMP
CAUTION: The pump is not equipped with a dry tank
shut-off switch. Turn the pump switch OFF if water in
tank becomes depleted or when system is not in use.
The pump operates when water pressure within outlet
plumbing drops below a predetermined pressure.
A drop in pressure occurs when a faucet or a toilet
valve is opened. When the faucet is closed the pump
shuts off as soon as the system is re-pressurized.
Turn the pump ON to pressurize the water system.
When the faucet is opened, the water may sputter
for a few seconds. This is normal and no cause for
alarm. The water flow will become steady when all air
is bled from the water lines. If a faucet is open slightly,
allowing water to flow slowly, the pump may pressur-
ize the plumbing faster than the water is released,
causing the pump to cycle on and off.
A built-in check valve prevents back flow and pro-
tects the pump and fresh water tank from excessive
city water system pressures. The pump operates at
2.8 GPM and 45 PSI. At free flow the pump draws
approximately 4 amps. A fuse in the power center
protects the water pump circuit.
When traveling, always turn OFF the water pump.
This will reduce the possibility of water flowing during
travel. If the pump cycles on and off when no water
is being used, you may have a partly open faucet, a
leak in the water system or an empty water tank.
Never attempt to service the pump without first turn-
ing off the power and opening all faucets to relieve
pressure in the water system. Consult the installation
and operation manual for full details in the Owner’s
Information Package.
WATER TANK FILL
The fresh water system should be sanitized at the ini-
tial filling, after a period of storage or if contaminated.
See “Sanitize Fresh Water System” in this section. Fill
tank slowly. Do not overfill. Do not leave unattended
while filling. Structure damage may occur.
Filling the fresh water tank:
1. Close water tank drain petcock located at the rear
or rear side of the trailer.
2. Remove cap on fresh water fill inlet.
3. Using a 3/8” hose adapter, fill the water tank
through the exterior fill spout slowly at a low
volume until water overflows out the vent. Do not
force water into spout since air in the tank must
be released during filling. Do not put the potable
water hose into the mouth of the fill.

4. Set pump control switch to ON.
5. Open each faucet one by one until water flows
evenly, and no air bubbles are evident.
6. Top off water tank through the exterior fill spout to
replace water used in filling the water heater and
purging the water lines of air.
7. Replace cap and lock the access door.
