Filling the Fresh Water Tank

Do not leave the motorhome unattended while filling the fresh water tank. Although
the fresh water tank has an overfill vent, incoming water volume may exceed the
capacity of the overfill vent, creating excessive pressure within the water tank and
possible damage to seals and fittings.
When an outside source of water is unavailable, water can be drawn from the fresh water
storage tank in the motorhome. This can be referred to as dry-camping.
1. Set your water heater bypass valves to the correct position listed on your water system
label
2. If your fresh water tank overflow valves are shut OFF or capped:
a. Open the fresh water tank overflow shut-off valves, or
b. Unscrew and remove the fresh water tank overflow valve caps
3. Remove the water fill cap
4. Water can now be added directly to the fresh water tank through the fill spout by use
of a clean potable water hose or a bucket that used only for this purpose. We do not
recommend using the same bucket to fill your potable (drinking) water tank and perform
maintenance tasks, etc.
5. When the tank is full and water is coming out of the fresh water overflow tubes located
under your motorhome:
a. Stop filling the fresh water tank
b. Replace the water fill cap
c. Allow water to continue to flow from the fresh water tank overflow tubes until the
water pressure equalizes and there is no more water coming from the overflow tubes
To use water from the fresh water tank, turn the water pump ON to pressurize the water in the
