Section 8: Plumbing System

You should always use a non-toxic drinking water hose
dedicated only to supplying the motor home with fresh
water through the city water connection inlet. To reduce
the chance of contamination, prevent the non-toxic
drinking water hose from coming into contact with the
ground. Install the city water connection inlet cap when
the city water connection is not being used.
The City Water Connection should be unplugged
(i.e., the non-toxic drinking water hose disconnected)
when the motor home is unattended for any amount
of time. If something would happen to the water system, this may help limit water
damage to a smaller area.
Do not remove this label from your motor home:
Water Control Valve Operation
City Fixtures:
Use this setting if the motor home can be hooked
up to an external pressurized water source (referred to as “city
water”).
If needed, sanitize the water system prior to travel.
1. Move the water heater bypass valves (if equipped) to the
NORMAL position (supply line valves ON, middle mixer
valve OFF). The tankless water heater has no bypass.
2. Remove the city water connection inlet cap and attach a non-
toxic drinking water hose to the city water connection inlet
and the other end to a pressurized water source.
3. Place the utility center valves in the “CITY FIXTURES”
position.

.
4. Turn ON the water at the external water source.
5. Enter the motor home and open the cold water supply
faucets to bleed air from the water lines. When the
water lines are nearly full, you may experience some
“air pockets.” Allow these to escape before closing
the cold water supply faucets.
6. The tank (storage) water heater (if so equipped) will
fill first, followed by the supply lines and faucets.
7. Turn the (12-volt GAS or 120-volt ELECTRIC) storage water heater power switch ON.
For a tankless water heater, turn the water heater power switch (located outside at the
water heater panel) ON. The water will be heated on demand.
NOTE: A short hose is supplied with your motor home for use
in sanitizing or winterizing the water lines in your RV. It can also
be used to siphon fill the fresh water tank when no city water is
available. One end of this hose has a fitting that will screw onto the
city water connection inlet allowing the other end to be put into a
container of fresh water, sanitizer or RV antifreeze (refer to
Sanitiz-
ing and Winterizing).
