use will not alter the taste of the water. To connect the city water supply to the motor home,
connect one end of the power retractable hose (Figure 11-7) to the city water supply; this
connection will usually be to a faucet or valve similar to your garden hose valve at home.
Turn the city water supply “on” for a few seconds to clear the line. Once the
hose has been flushed, turn the supply “off.” Connect the other end of the
hose to the city-water connections on the motor home.
Once the city water fill valve is opened, water is supplied to the freshwater
system including the hot water heater, faucets, and toilet. Turn “on” the water
supply and open all of the faucets to clear any trapped air within the plumbing
lines within the motor home.
Once any air pockets have purged from the water lines and water flows freely,
close all of the faucets. The city water supply is pressurized (usually 60-80 psig);
therefore, the water pump is not needed when the water system of the motor
home is connected to the city water system.
To disconnect the motor home from the city water supply, close the valve and remove the hose from the
city water supply. Disconnect the hose from the city water connection, drain it, and store the hose in the
water compartment of the motor home.
Filling the Freshwater Tank
The freshwater tank is normally filled from the city water connection. The city-water valve (Figure
11-8) located in the sanitation compartment near the water connection determines whether the city
water is going through the motor-home 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 motor home.
The excess water will be vented from an overflow in the 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 motor
home is not in use for an extended period of time.
Sanitizing
To assure complete disinfecting of the freshwater system, it is recommended that the following
procedure 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:
