P-TRAPS
WASTEWATER DISPOSAL
Each of the sink drains and the shower drain has a water trap (P-trap) to prevent holding-tank odors
from entering the vehicle.
Th
ese traps must have water in them to trap odors. When the vehicle is in motion, the water may splash
out of the sink and shower drains. When the vehicle is stored, the water may evaporate from these traps
allowing odors to enter the vehicle. If this occurs, run water from the faucet into the drain, allowing
water to
fi
ll the traps again.
Both of the holding tanks terminate in a valve
arrangement that permits draining each tank
separately or together. It is recommended to
drain the black-water tank
fi
rst before drain-
ing the gray-water tank.
Th
is procedure per-
mits the water from the gray tank to wash the
black-water residue from the drain lines and
hose found in the external sanitation com-
partment.
Th
e valves that open to release the water are
called gate valves.
Th
e blade that closed the
opening in the sewer drainpipes is connect-
ed to the T-handle to release contents of the
tank(s) when pulled.
Th
e sewer line must be
securely capped during self-containment use to prevent leakage of waste materials. Do not pull the
holding tank gate valve “open” when the protective cap is installed on the pipe.
Always drain the tank into an acceptable sewer inlet or dump station. Whenever possible, drain both

NOTICE
Use only RV odor-controlling chemicals in the
holding tanks. Products containing ammonia and
petroleum will damage the ABS plastic holding
tanks and seals. It is important that you use as
much water as possible each time you flush the
toilet. This will help prevent tissue and other sol-
ids from clogging the holding tank outlet.
