vented to prevent waste gases from entering your motorhome. The drain piping is
made of ABS material and is resistant to most chemicals. The “P” traps at the sinks,
showers and tubs are available for use as clean-outs if necessary.
Your vehicle’s holding tank compartments are heated by the furnace duct work. It will
heat the tanks when the furnace is operating.
As mentioned previously, your holding tanks terminate together at one location for
convenience in dumping your tanks. A twist-on cap is located at the terminal outlet
to help prevent leakage of materials.
The holding tanks are enclosed sewer systems, and must be
drained into an approved dump station. Tanks should be
thoroughly drained and rinsed to prevent any accumulation
on the interior of the tanks.
1. Twist off the termination cap counterclockwise. Some liquid may be trapped
between the valves.
2. Connect the sewer hose by turning it clockwise, making sure that the connection
end levers are locked over the termination end.
3. Deposit the other end of the sewer hose into an approved dump station inlet.
4. Open the black termination valve fi rst and drain.
5. Open the gray (smaller) tank valve to drain and fl ush out the hose.
6. Rinse the tanks and hose thoroughly with fresh water before disconnecting.
7. Close the termination valves.
8. Rinse the sewer hose with the faucet provided in the termination
compartment.
9. Replace the sewer hose to the storage location.
10. Replace the termination cap on the outlet, making sure that it is secured and
locked.

You may wish to add an approved deodorant chemical, approved for your
sewer system, to aid in the breakdown of solid wastes as well as making
your system more pleasant to use.
Do not leave the termination valves in the open position or open
them prior to having the sewer hose connected. Do not remove the
termination cap with the termination valves in the open position.
The most common holding tank problem is blocking the drain lines, which can be
minimized by following a few simple suggestions:
• Prior to dumping, make sure your tank is at least 1/3 full.
• Keep the tank valves closed, and the termination cap on.
• Fill and cover the bottom of the tank with water after dumping is complete and
leave the water in the tank.
• Use only approved, biodegradable, toilet tissue designed specifi cally for mo-
torhome systems.
