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 above instructions
before using.
All drain pipes from sink and shower will have a “P-trap” installed into
each line. Water in these traps prevent odors from escaping into the
coach. During travel, water from the P-traps may spill and permit odors
into the coach. These odors come from fats and food particles
decomposing in the tank. By adding water and using a RV approved
deodorizing agent, contents will dissolve faster, keeping the drain lines
and tanks clean and free flowing. These chemicals are available at a RV
supply store.
Draining the Tanks
A final part of your sanitation system is the drainage of holding tanks.
Realizing dump stations will vary, place the coach as level as possible to
make drainage easier. Some tanks drain from the center requiring level
or slightly higher in the front. Others will drain from end permitting a slight
tilting to the side which drains are on.
Make sure the Dump Valves are closed before removing the cap and
attach the adapter onto the valve housing. Turn the adapter 10º to lock
onto the pegs. Attach a flexible sewer hose to the adapter and secure
with a clamp. Place the other end into the approved sewer system.
You may now open the valve to drain the sewage tank first. Open the
valve on the gray water tank last to utilize water to wash and rinse the
hoses and drain lines.
NEVER leave the gate valve of your coach’s sewage tank
open when hooked up to a park’s sewer system. Open only
when you need to drain the system.
