Water Systems
SECTION SEVEN
Fresh Water System:
The fresh water system consists of a fresh water tank,
water pump and gravity fill inlet . Obtain a supply hose
made for potable water use only . Proper care of the
hose is necessary . After each use, drain the water hose
and screw the ends together for sanitary purposes .
The onboard water pump uses water from the fresh
water tank when a faucet is opened or the toilet is
flushed . Use water sparingly when not hooked to shore
service .
Improper winterizing, poor maintenance, road vibration
and campsite water pressure variations are common
culprits of water system problems or failure . Check all
plumbing connections for leaks at least once a year .
Waste Water System:
The sinks and shower drain into the grey water holding
tank . The black water tank is dedicated for the toilet .
Normally these tanks are proportionate in size to the
fresh water tank . If a camping trip is started with a full
fresh water tank, the waste holding tanks will be full
or nearly full when all the water is used from the fresh
water tank .
Prior to using the toilet, add several gallons of water to
the black tank to help prevent accumulation of solids .
Holding tank odor control chemicals are available at
most RV supply outlets .
TANK MONITOR
A monitor panel will aid in managing the storage tanks .
The monitor panel is located on the panel located in
the hallway area . Press the corresponding switch to
test the level of a storage tank . The scale uses colored
lights along with a corresponding scale reading .
Tank Monitor:
• Press the Levels Test button to obtain a readout .
WATER — POTABLE
The motorhome is equipped with a fresh water holding
tank and an on-demand water pump . The water pump
pressurizes the fresh water system . When city water
is available, city water will pressurize the fresh water
system and the water pump can be left off . A water
pressure regulator must be installed to limit incoming
city water pressure to the fresh water system to no
more than 45 psi .
There are two methods of supplying fresh water to
the motorhome:
• Use a potable water hose connected to a water
source .
• Water is added directly to the fresh water tank via
the gravity fill .
WARNING:
Water is electrically conductive . Do not use any
electrically powered item or electrical outlet that
may be exposed to a water source . Electrical shock
can cause serious injury or death .
NOTE:
Some units are equipped with a standard monitor
panel . Others are equipped with these functions
on the multiplex touchscreen .
CAUTION:
External water sources can deliver water pressure,
particularly in mountainous regions . High water
pressure is anything over 55 psi (pounds per
square inch) . Excessive water pressure can cause
leaks in water lines, damage appliances and cause
the potable water hose to swell and burst . Attach a
pressure regulator at the city water faucet to limit
water pressure to 45 psi .
