Sewage (black) tank preparation
1. Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
2. Pour the recommended quantity of holding tank chemical (customer supplied) into the toilet bowl, per the man-
ufacturer's directions.
3. Flush the toilet and allow at least two gallons (8 liters) of water to flow into the holding tank.
Waste (grey) holding tank preparation
No special preparation is required, however, placing a small quantity of chemicals into this tank, such as baking soda
or an approved RV chemical, will reduce odors from food particles in the system.
Cleaning and maintenance
Clean the toilet regularly. DO NOT use chlorine (undiluted) or caustic chemicals in the toilet system (ie., laundry
bleach or drain opening chemicals). These products damage the seals in toilets and dump valves. For a sticky toilet
ball valve, apply petroleum jelly; this will provide waterproof lubrication without damaging the seals.

Your RV may be equipped with a dry sealing valve that prevents the escape of odors from your waste system and
eliminates the need for P-traps. Should the RV drain piping system become clogged and a mechanical clean-out
tool is used to open the drain pipe, it is important that the dry valve be removed before passing the clean-out tool
through the piping. Passing a mechanical clean-out tool through the waterless valve may cause damage to the internal
seal that may potentially allow sewer gases to escape to the RV interior

The drain pipes may be equipped with a P-trap installed to help prevent odors from escaping into the RV. During trav-
el, water from the P-traps may spill and permit odors into the RV. By adding water and using a RV approved deodor-
izing agent you will dissolve the contents faster and will keep the drain lines and tanks clean and free flowing. These
chemicals are available at an RV supply store or your dealer.
V E N T S & V E N T P I P E S
Another important part of this system is the vent pipes and vents that release air from the grey and black water hold-
ing tanks. The exterior vent cap is attached to the roof and must be kept clear of obstructions to perform as intended.
On some models, the vent pipe may be part of the drainage system referred to as a wet vent (water flows downward
as air flows upward in the same pipe).

When connected to the sewer drain line at a campground, keep the black tank drain valve closed until the holding
tank is at least

full. This should provide sufficient water to assist in complete draining of the black water holding
tank. Repeat as needed. Never leave the black tank drain in the open position continuously when connected to the
campground sewer system.
