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 coach. 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 waste
holding tank. Certain floor plans may also have the lavatory draining into the waste (sewage) tank.
Sewage Tank Preparation
1. Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
2. Following 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 (8 liters) 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 a Thetford chemical, 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 calculated 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 holding tank(s), together with cargo you have added, may exceed the
GVWR of your trailer, causing towing difficulties and resulting in property damage
or personal injury.
DRAINING THE TANKS
On the outside of the trailer are labels (Fig. 4-12 & 4-13) that indicate the location of the gray and
black holding tank drain. A typical set up of the tank drain and termination valves is indicated in
