Typical fresh water gravity fill
Filling the Fresh Water Tank
When an outside
source of water is
unavailable, water
can be drawn from
the fresh water
holding tank in the
motorhome.
1. Set your water
heater bypass
valves to the
correct posi-
tion listed on
your water
system label.
DO NOT
OPERATE
THE WATER
HEATER IF
ITS WATER
SUPPLY IS
BYPASSED.
2. If your fresh water tank overow valves are shut OFF
or capped:
a. Open the fresh water tank overow shut-o valves;
or,
b. Unscrew and remove the fresh water tank overow
valve caps.
3. Remove the water ll cap.
4. Attach a potable water hose to the gravity ll inlet,
while attaching the other end of the hose to a source
of safe drinking water. Turn ON the valve at the water
source. Only use a water hose designated for potable
water purposes.
5. When the tank is full and water is coming out of
the fresh water overow tubes located under your
motorhome:
a. Stop lling the fresh water tank;
b. Replace the water ll cap.
To use water from the fresh water tank, turn the water
pump ON to pressurize the water in the lines and to the
water heater. When ready, gradually open the hot and cold
water at the sinks and tub to clear air from the lines. Close
the faucets when the water is owing freely.
When traveling, it is good practice to only carry a quantity
of fresh water that will meet your fresh water needs until
arriving at your next destination with a safe, potable water
source. is will reduce the total weight of your motorhome,
allowing for carrying capacity for other items, if needed.
Refer to Section 6, Occupant and Cargo Carrying and
Capacity (OCCC).
NOTE: While traveling, water can slosh in the fresh
water tank and a small amount may escape through
the overflow tube. This is a normal occurrence and
you should not be alarmed if you arrive at your desti-
nation with less fresh water than you expected.
Water Pump
When the motorhome is not connected to city water (e.g.,
campsite water) and you want to use water from the fresh
water holding tank, you will need sucient 12 volts DC
power to operate the water pump. Once turned ON at
the monitor or multiplex or panel, the water pump (also
known as an on-demand pump) will self-prime, pressurize
the water lines, and provide water to the faucets, shower,
and toilet. As long as the water pump switch is ON, and
POTABLE WATER ONLY. SANITIZE, FLUSH, AND
DRAIN FRESH WATER TANK BEFORE USING.
Failure to maintain tank may result in death or serious
injury.
WARNINGWARNING
Do not leave the motorhome unattended while lling
the fresh water tank. Although the fresh water tank has
an overll vent, incoming water volume may exceed
the capacity of the overll vent, creating excessive
pressure within the water tank and possible damage to
seals and ttings.
NOTICENOTICE
• Do not turn the water pump ON if the fresh water
tank is empty. Doing so could cause damage to the
water pump.
• Do not turn ON the water pump when using water
from an external source. Only run the water pump if
using potable water stored in your fresh water tank.
• The water pump should be turned OFF when the
motorhome is left unattended for any amount of
time. This may help limit potential damage should
something fail within the water system.
