4-12 Fresh Water System________
________________________
4-12.1 Water Supply and Distribution System
The fresh water tank is approximately 100
gallons. The dual purpose Tank Water
Fill/Municipal Water inlet connection is
located in the road side holding tank
compartment, in Bay 4, left. The Tank Fill On-
Off switch, located in Bay 4, left, diverts the
municipal water input to fill the pure water
storage tank, which is located in Bay 2.
System water pressure is provided by a water
pump located in the roadside compartment,
Bay 2, left. The fresh water tank is non-
pressurized with the system water pressure
developed by a demand pump when not
connected to a municipal water system. The
fresh water tank is equipped with a two inch
drain. The tank also includes level indicators,
located on the curbside end of the fresh water tank. All of the water supplied to the motor home is
filtered through an activated carbon filter.
4-12.2 Municipal Water Hookup
When facilities are available, the Municipal Water hookup can be used to supply all motor home water
system requirements. In this manner, the fresh water tank and pump system are automatically
bypassed with the water pressure regulated by the municipal water system (approximately 40 psi).
4-12.3 Filling and Draining
To fill the fresh water tank, connect the water hose to the municipal water inlet, set the Tank Fill
switch to ON, then turn on the water supply. When the tank is full, the level switch in the tank will
close the tank fill solenoid. Set the Tank Fill switch to the OFF position, shut off the water supply and
disconnect the hose. At this time, check that the Monitor panel readout indicates a full water tank. By
pressing the Pure tank switch and observing that all, E through F indicator segments are lit.
NOTE: The Tank Fill switch should be ON only when the water tank is being filled. This switch
must be in the OFF position at all other times.
4-12.3.1 Sanitizing
Water system sanitizing procedures should be followed before the system is used for the first time,
after long idle periods where water may become stagnant, or after any suspected contamination of
the water supply. Whenever possible, use a commercially approved tank sanitizer and follow the
procedures on the product package. If it is not possible to use a commercial product, prepare your
own mixture and sanitize the tank in accordance with the following procedures:
1. Empty the Fresh Water Tanks – To drain the tanks, open the 2-inch Cold Water Drain Valve
located inside the opening below the fresh water tank on the roadside, Bay 2, left. Pull valve
toward front of motor home. After the tank is completely drained, close the Cold Water Drain.
2. Prepare the Sanitizing solution – Each gallon of Sanitizing solution consists of ¼ cup of
household bleach (sodium hypochlorite) solution and one gallon of water. This mixture results
in a residual chlorine concentration of 50 ppm in the water system. Seven to eight gallons of
