Never travel with full black or grey water
holding tanks. Dump the black and grey
water holding tanks before traveling to
avoid carrying unnecessary weight. This
not only wastes your tow vehicle fuel but,
depending on location of the tank(s), can
affect
your
tow
characteristics.
The RV black and grey water holding tanks
use gravity flow (they are not mechanically
pressurized) during the dumping process.
If it's time to leave the campground and your
holding tanks aren't full, finish filling them with
water and then dump them. Driving to a
disposal site with sufficient liquids in the
holding tanks will normally loosen any
accumulated waste debris or solids from the
sides of the holding tanks. If you are dry
camping and cannot immediately empty your
holding tanks, reduce your vehicle speed until
you reach a dumping station.

Before using the RV, or after dumping the
grey and black water holding tanks, always
add the proper amount of deodorant to the
black water tank to prevent malodors and help
break down holding tank contents (unless
winterizing).

□ Follow the directions on your toilet
chemical bottle (customer supplied), by
placing the recommended quantity of
holding tank chemical into the toilet bowl.
□ Flush the toilet and allow at least an
additional two gallons (8 liters) of water to
flow into the holding tank.
Waste (grey) holding tank preparation
Remove residue before washing dishes to
keep food and grease out of the pipes. Over
time and usage, grease and residue will build
up in the grey tank. You may notice a foul
odor from food particles in the system, and a
difference in the tank and valve assembly
operation. Periodically treat the grey tank with
environmentally safe holding tank chemicals
to avoid odors from the tank. Avoid using
chemical drain openers that may contain
corrosive agents that can damage fixtures.
Most states and parks have strict laws and
regulations to prohibit dumping of wastes
of any kind into anything other than proper
disposal facilities or sewer systems. Almost
all privately owned parks offer a campsite
hookup for sewage. You can locate many
dump stations throughout the United
States and Canada in Woodall's, Rand
McNally Camp Guide, Good Sam Camp
Guide, KOA Kampgrounds Camp Guide
and various other publications. Some fuel
stations also have dump stations.

The black tank termination valve and the grey
tank termination valve (also called dump
valves) are located in the universal docking
center. They are used to drain the RV black
tank and grey water tank.
□ When connected to the sewer drain line at
a campground, keep the "black water
termination valve" closed until the holding
tank is at least ¾ full. This should provide
sufficient liquid to assist in complete
draining of the black water holding tank.
