FILLING THE FRESHWATER TANK
SANITIZING
The freshwater tank is normally filled from the city water connection. The valve located in the service
compartment near the water connection determines whether the city water is going through the water
system or into the freshwater tank. Since there is not an automatic shut-off when filling the freshwater
tank, check the level from the monitor panel while filling the freshwater tank on the motorhome.
The excess water will be vented from an overflow in vent pipe onto the ground when the capacity of
that tank has been reached. This pipe is installed in the freshwater tank to prevent possible tank rupture
from inadvertent overfilling.
All of the water should be drained from the freshwater system when the motorhome is not in use for
an extended period of time.
To assure complete disinfecting of the freshwater system, it is recommended that the following proce-
dures be performed on a new system, on one that has not been used for a length of time, or one that
may have become contaminated. This procedure is also recommended before long periods of storage,
such as during the winter months:
1. Drain the freshwater tank by opening the drain valve. All of the faucets should be in the closed or
“off” position.
2. Prepare a chlorine solution using one gallon of water and one-half cup of chlorine bleach (5% so-
dium-hypochlorite solution). Prepare enough of the chlorine solution to administer one gallon of solu-
tion for every 15 gallons of tank capacity. For sanitizing this unit, prepare 4½ gallons of the chlorine
solution. This mixture puts a 50 ppm (parts per million) residual chlorine concentration in the water
system that will act as a quick-kill dosage for harmful bacteria, viruses, and slime-forming organisms.
Concentrations greater than 50 ppm may damage the water lines and/or the tank.
3. Once the freshwater tank is empty, close the drain valves in the water tank.
4. Pump the chlorine solution into the tank by taking the hose attachment and attaching it to the
pump and then put in the chlorine solution. Close the valve from the fresh water tank to the pump and
open the valve from the solution to the pump. Turn the tank fill valve from “city water” to “tank fill.”
Turn “on” the water pump until all of the solution is pumped into the fresh water tank.
5. Turn “off” the water pump. Open the valve from the tank to the water pump. Fill the water tank
with the city water tank fill (or by using the same method as was used to put the sanitizing solution into
the tank). Remove the water filter (from the drink dispenser faucet, if installed). Open each faucet, in
turn, including the kitchen faucet, bath faucet, inside and outside showers, turning “on” both the hot
and cold faucets and flushing the toilet until all of the air has been purged from the pipes and the water
runs freely. The entire system will then be filled with the sanitizing solution.
