plumbIng systems and
holdIng tanks
The plumbing systems in your motor home are
constructed of durable thermoplastic materi-
als . Holding tanks and piping components are
strong, lightweight, and corrosion resistant .
Holding tanks are of three types:
• Fresh – Fresh potable water
• Grey – Lavy/shower effluent
• Black – Toilet effluent
It is recommended to discharge as many fluid
tanks as practical before driving .
fresh water system
Fresh, potable water is available from either an
external “city water” hookup or on-board storage .
External Fresh Water Hookup
The external system is pressurized by the water
system at an RV park or city water supply . The
connection is located in the utility compartment
on the rear left side of the motor home .
To connect to pressurized city water:
1 . Connect one end of a potable water hose to
the RV park or city water supply . This will
usually be a faucet or valve similar to your
garden hose valve at home . Potable water
hoses are available at RV supply stores .
2 . Run the city water supply for a few sec-
onds to clear the line . Turn off the water .
3 . Attach the other end of the potable water
hose to city water connection located on
the motor home . Make sure all connections
are tight .
4 . Turn on the RV park/city water supply .
Open all faucets inside the motor home to
clear the lines . Then turn off faucets .
To disconnect the city water:
1 . Turn OFF the city water supply .
2 . Remove the hose from the city water supply
valve .
3 . Drain and store the hose .
Filling the On-Board Water Tank
The on-board fresh water tank can be filled in
two ways: (1) city water pressure or (2) grav -
ity.
1 . City water pressure – When connected to
the city water supply as described above,
turn the bypass valve located in the utility
compartment to “Water Tank Fill” from
the “Normal” setting. This will fill the on-
board fresh water tank .
Make sure the external gravity fill connec -
tion is open (remove the cap) to allow air to
escape from the on-board tank . When water
just starts to flow out of this external fill, the
on-board tank is full . Immediately shut the
water off or turn the bypass valve to normal .
After filling, turn the bypass valve to
“Normal .”

External Fresh Water Connection
Since water pressures at campgrounds vary, we rec-
om mend you install an in-line pressure regulator (if
not equipped) at the water supply faucet. This will
protect the motor home water system and your supply
hose from excessively high water pressure.
