Refer to the toilet manufacturer’s owner’s manual in your Owner’s Package for complete instructions and
a troubleshooting guide.
P-Traps
Each of the sink drains, the shower drain, and the washing machine drain (if equipped) has a water trap
(P-Trap) to prevent holding tank odors from entering the coach. These traps must have water in them in
order to trap the odors. While traveling, the water may splash out of the sink and shower drains. While
stored, the water may evaporate allowing an odor to enter the coach. If this occurs, run water from the
faucet into the drain, allowing water to fill the trap.
Black Water Holding Tank
The black water, or sewage, holding tank is located directly beneath the toilet. Before using the stool, you
will need to treat the tank with water that is mixed with an odor controlling chemical. These chemicals are
readily available at any RV supply store. Be careful not to spill the chemical on your hands, clothing, or
the carpet because it may cause a permanent stain. Add water to the toilet, and add chemical to mix with
the toilet water. Continue run water into the toilet and through down to the tank until at least one inch of
solution is directly under the toilet. Discontinue adding water; the waste tank is now ready for use.
CAUTION
Use only approved RV odor controlling chemicals in the holding tanks. Products containing ammonia and
petroleum will damage the ABS plastic holding tanks and seals.
Gray Water Holding Tank
The gray water holding tank is located in the underbelly of the unit. It is primarily used for the drainage
from the kitchen and bath sinks and the shower.
Waste Water Disposal
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 before the gray water tank. This will allow the
water from the gray tank to wash the black water residue from the drain lines and hose. The valves that
open to release the water are called gate valves.
The blade that closed the opening in the sewer drain pipes is connected to the T-handle to release the
contents of the tank(s) when pulled. The sewer line must be securely capped during self-containment use
to prevent leakage of waste material onto the ground or pavement. 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.
The holding tanks should only be drained when they are at least 3/4 full. Doing this will provide sufficient
water to allow the complete flushing of waste materials in the drain lines and hose. If the tanks are not 3/4
full, add enough water to allow for sufficient flushing.
