48
seconds or more to ensure all solids and wastes move into tank and are
not held in drainage pipes.
Operation
To flush, press pedal all the way down. To add water, press pedal halfway
down.
When hooked up to a sewer drain at a camp ground, ALWAYS keep the
termination valve CLOSED until the tank is at least 3/4 full. This will
provide sufficient water to assist in complete draining of tank.

Using Toilet and Tank System
When camping you should always have 4 to 6 inches of water in the toilet
bowl. The toilet system performs better when you run water 10 to 20
seconds after flushing to ensure wastes will proceed to the bottom of the
tank. Unlike your toilet at home which uses four to seven gallons per
flush, the average recreational vehicle system uses two to three quarts.
If there is not sufficient water used during flushing, waste materials may
not evacuate properly from drain line to tank. Tank and pipes could
eventually become clogged.
Vents
A very important part of your sanitation system is the vent system in your
coach. These vents release air from holding tanks allowing water to
enter. Vent pipes are attached to the holding tank, go through the walls
and cabinets to the roof. On some models, a portion of vent pipe may be
part of the drainage system referred to as a “wet vent”. As air flows
upward, water will be draining downward.
On several floor plans a side vent for grey holding tank replaces the
normal “mushroom” vent cover on the roof. A louvered vent covers the
opening in the sidewall. Piping for vent is attached from holding tank
directly to vent opening in sidewall, not using a “wet” vent.
By keeping valves closed in holding tank(s), sewer gases are prevented
from escaping through side opening. Absence of cabinetry from floor to
ceiling is cause of side vent usage verses roof vent.
Keep drain valve closed. Sewer gases may be present when
RV is connected to campground sewage hookup. If drain
valve is open, sewer gases may be vented out the side of the
RV. (See owner’s manual.)
