the tank (see directions for draining below) 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.
To empty tank:
1. Place travel trailer as level as possible to make drainage easier.
2. Attach a flexible sewer hose to adapter and secure with a clamp.
3. Remove cap and attach adapter onto valve housing.
4. Turn adapter 10° to lock onto pegs.
5. Place other end into approved sewer system.
6. Open the 3" drain valve to drain the sewage tank.
7. Open the valve on the gray water tank to utilize the water to wash and rinse the
hose.
All drainpipes have a "P-trap" installed into each line. Water in these traps prevent odors
from escaping into the travel trailer. During travel, water from the P-traps may spill and
permit odors into travel trailer. These odors come from food particles decomposing in the
tank. By adding water and using a RV approved deodorizing agent the contents will
dissolve faster and will keep the drain lines and tanks clean and free flowing. Chemicals
are available at an RV supply store.
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 have either a central pump facility or offer a campsite hookup of
sewage. You can find lists of many dump facilities throughout the United States 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.
