-Typical View
Black and Gray Waste Tank Drain Valve positions may
be reversed, depending on floorplan and tank location
NOTE: The sewage drain outlet swivels
downward (on certain models) when
necessary to avoid bends in the sewage
drain hose, which could trap solids while
dumping, or to provide more direct
drainage while using on-site sewer hook-
ups.
3. Place the outlet end of sewage drain hose into
disposal opening.
4. Open the Black Waste Tank Drain Valve with
a quick pull and make sure there are no sags in
the hose. Move the hose gently about to
dislodge any waste and ensure complete
drainage. Close Black Waste Tank Drain
Valve as soon as tank is empty.

-Typical View
NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste
Tank Drain Valve until the black tank is
drained and Black Waste Tank Drain
Valve closed to avoid sewage back-up
into gray tank. Gray water also rinses
any black water solids from the sewage
drain hose.
5. Open the Gray Waste Tank Drain Valve. Be
sure there are no sags in the hose to ensure
complete drainage. Close Gray Waste Tank
Drain Valve as soon as tank is empty.
6. Add an odor control chemical to the sewage
holding tank through the toilet(s). These
chemicals are available at most RV supply
centers.
7. Rinse sewage drain hose thoroughly with
water before stowing.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
Flushing your Black Water Holding
Tank
The black water holding tank is equipped with
an internal spray head that allows you to rinse the
inside of the tank with a shower of clean water
after dumping.
