Water System (Self-Contained)
Fill the water tank by opening the exterior access door
and remove screw cap� A drinking water safe hose
can now be inserted� It's a good idea to let the water
run through the hose for a short time to flush it out.
Experienced RVers usually fill their tanks with "home"
water to avoid strange water that may be distasteful to
them� The amount of water in the tank may be checked
on the Monitor Panel, or you may fill the tank until
water overflows out of the fill.
Open the hot side of the galley or lavatory faucet
and turn on the water pump switch located on the
monitor panel� For a short time, the open faucet will
only sputter� This is because air is being pushed out
through the lines� Now, open a cold faucet� It will
sputter for a short time, but will soon expel a steady
stream� All other faucets can now be opened until all
air is expelled. Once the system is filled with water
and the faucets closed, the water pump will shut off�
When a faucet is opened, the pump will come back
on automatically� If the faucet is just barely open, it is
normal for the pump to cycle on and off rapidly�
Water Pump
The water pump switch (monitor panel mounted, see
Appliances in this section) operates the pump� Once
the switch is turned on, the pump will run until the
water pressure reaches about 55 psi�
At this point, an internal pressure switch will shut it off�
When a faucet is opened, the water pressure will drop
and the pump will start to run again�
As a general rule, the water pump should be turned off
while using a city water hookup; however, the water
pressure at some campgrounds may be low� The water
pump can be turned on to assist the city water hookup
pressure� Be sure there is some water in the fresh
water tank� The pump will only use the water that is
needed out of the tank to bring the pressure up to the
usual standard of 55 psi�
Access to the water pump will be necessary for
periodic cleaning of the strainer screen� Refer to
Section 8 - Maintenance for water pump access and
strainer screen removal�
NOTE
Turn off the water pump while traveling to prevent
water from being pumped in the event a faucet
opens in transit.

Draining System
Fresh Water Lines and Tanks
Fresh water drain valves consist of low point water line
drain valves and fresh water tank drain valves� The
valves are in-line or petcock-type valves�
Refer to Section 8 - Maintenance for necessary drain
valve locations and draining procedures of fresh water
lines and tanks�
Drain and Waste System
Your trailer has a drain and waste system that includes
waste-holding tanks made from corrosion-free, molded
plastic, with trouble-free dump valves�
The main (Black Water) holding tank enables you to
use the toilet for several days away from disposal
facilities� The wastewater from the sink, shower, bath
and lavatory drains into the auxiliary (Gray Water)
holding tank�
Each tank has its own dump valve with both tanks
draining through a common outlet� Therefore, only one
sewer hose connection is needed when hooking up to
a dump station�
Almost all campgrounds will have dumping facilities�
Park directories, such as Woodalls and Rand McNally,
also list dumping stations�
Refer to Section 8 - Maintenance for important
information on Black and Gray Water tanks draining,
cleaning, and rinsing procedures�
Check your monitor panel frequently. When the Black
Water holding tank is completely full, sewage cannot
be emptied from the toilet bowl� If the Gray Water
holding tank is overfilled, drain water may back up into
the shower floor pan and cause an unpleasant cleaning
job� Never drain the tanks at any place other than an
approved dumping station�
NOTE
Never put wet strength paper towels or tissues
in your holding tank since they won't dissolve
and can catch in the mechanism of the dump
valve. Colored toilet tissue is slower to dissolve
than white. Most RV-accessory stores offer tissue
designed for RVs that will completely dissolve.
