Vents
A very important part of your sanitation system is the vent system in
your coach. These vents release air from holding tanks allowing
water to enter. Vent pipes are attached to the holding tank, go
through the walls and cabinets to the roof. On some models a
portion of vent pipe may be part of the drainage system referred to
as a “wet vent”. As air flows upward, water will be draining
downward.
On several floor plans, a side vent for grey holding tank replaces the
normal “mushroom” vent cover on the roof. A louvered vent covers
the opening in side wall. Piping for vent is attached from holding
tank directly to vent opening in side wall, not using a “wet” vent.
By keeping valves closed in holding tank(s), sewer gases are
prevented from escaping through side vent opening. Absence of
cabinetry from floor to ceiling is the cause of side vent usage verses
roof vent.
Holding Tanks
The final parts of your sanitation system are the holding tanks for
waste materials and water. These are located below the floor of
your coach.
Gray Tank. Waste water from the bath tub, shower and sinks will
drain into this container. No special preparation is required,
however, you may wish to add baking soda or a Thetford chemical
to reduce odors from food particles in the system.
Waste Tank. The toilet drains into the waste or “black” holding tank.
For correct preparation follow the listed steps:
1. Release two quarts of water into the toilet bowl.
2. Place the recommended quantity of chemicals for waste holding
tank as per instructions on the bottle into the toilet bowl.
3. Flush liquids into the tank and allow up to two gallons of water to
flow into the tank.
Each time you drain the tank, you should follow the instructions
listed, before using.
All drain pipes will have a “P-trap” installed into each line. Water in
these traps prevent odors from escaping into the coach. During
