Vents
Another important part of the sanitation system are the vents which release air from
tanks. Each tank has a vent pipe built into the travel trailer through the cabinet, wall and
roof. A vent cap is attached to the roof and must be clear of obstructions to perform as
intended. On some models the vent pipe may be part of the drainage system referred to as
a “wet vent.” This means water flows downward as air flows upward in the same pipe.
Holding Tanks
The final part of your system are the holding tanks. They hold waste and are located
below the floor of your travel trailer. The bath tub and sinks drain into the waste water
tank, also referred to as the “gray” water holding tank. The toilet drains into the sewage
holding tank, also referred to as the “black” holding tank. Certain floor plans may also
have the lavatory draining into the black holding tank.
BLACK HOLDING TANK PREPARATION
1. Release one to two quarts of water into the toilet bowl.
2. Follow the directions on your toilet chemical bottle by placing the recommended
quantity of holding tank chemical into the bowl.
3. Flush the toilet and allow at least two gallons of water to flow into the tank.

CAUTION:
It is important to add enough water to prevent solid waste build
up. Follow these directions each time after emptying your holding tank,
except when winterizing.
GRAY WATER HOLDING TANK
No special preparation is required. However, placing a small quantity of chemicals into
this tank, such as baking soda or an approved concentrated holding tank deodorant, will
reduce odors from food particles in the system.

WARNING: We recommend that you DO NOT travel with waste in
your holding tanks. The weight of holding tank contents are not calcu-
lated into the cargo carrying capacity of the unit and the extra weight will
greatly diminish the cargo weight available to you, possibly causing you to
exceed the gross vehicle weight rating of the unit. This can damage suspension
components, such as springs, tires and axles. If your model has the holding
tanks located behind the axles, the weight of a full tank will reduce the hitch
weight. Sway and other handling difficulties can be the result of the hitch
weight being too light. If you are dry camping and cannot immediately empty
the tanks, use caution when towing and maintain lower speeds for better
control of the trailer until you reach a dumping station. Towing your trailer
with one or more full or nearly full tanks, together with cargo you have added,
may exceed the GVWR of your trailer, causing towing difficulties and result-
ing in property damage or personal injury.
SANITATION SYSTEM
Toilets
OPERATING INSTRUCTIONS – AQUA MAGIC
®
4
The Aqua Magic
®
4 is equipped with two operating levers
located on the right side of the toilet when facing the unit. To
flush, pull the black flush lever forward (clockwise) until
rinse clears the bowl and release the lever slowly. The
movement of the black flush lever opens the waste valve and
allows waste to pass into the holding tank. The water fill is
activated simultaneously with the black flush lever. The black
flush lever should be held open for several seconds to allow
adequate flush water coverage of bowl to develop. The white water fill lever can be
operated independently of the black flush lever if more than the normal two inch
automatic bowl refill water is desired.
YOU MUST USE AN ADEQUATE AMOUNT
OF WATER WHEN FLUSHING TO PREVENT SOLID WASTE BUILD UP AND
PROMOTE PROPER DRAINAGE.
See Holding Tanks.
Maintenance
Please refer to “Toilets: Maintenance” in Chapter 8.
Using Toilet System
NOTE
:
For added convenience and better sanitation system performance, it is
advisable to always have four to six inches of water in the toilet.
Prior to using the sanitation system, it is strongly recommended to flush the toilet
several times and release sufficient water into the tank. If there is not a sufficient
amount of water used during flushing, waste materials may not evacuate properly
from the drain line to the tank. A clogged tank and pipes could eventually occur.
When camping, you should always have four to six inches of water in the toilet bowl. The
toilet system will perform better when water is run for ten to fifteen seconds after
flushing to ensure wastes will proceed to the bottom of the tank. Unlike your toilet at
home which uses four to seven gallons of water per flush, the average recreation vehicle
system uses one to three quarts.
When hooking up to the sewer drain line at a campground, keep the termination valve on
the waste tank CLOSED until the tank is at least 3/4 full. This will provide sufficient
water to assist in complete draining of the tank. At this time, open the termination valve
to empty the tank and close the valve when the tank is empty. Repeat this process as
needed, but NEVER leave the termination valve open when hooked up to the park’s
sewer system.
