into gray tank. Gray water also rinses
any black water solids from the drain
hose.
NOTE: Black and Gray tank valve positions may
be reversed depending on floorplan and
tank location.
4. Open waste water dump valve (gray handle)
with a quick pull. Close valve handle as soon
as tank is empty.
5. After both tanks have been drained, flush the
black water tank as described in ‘Flushing
Your Black Water Holding Tank’ following
this procedure. (If hose is not available, run
several gallons of water into the sewage tank
through the toilet. Then open sewage dump
valve and drain the tank again. Close valve
when done.)
6. Close hose valve by pulling handle up until
lock snaps into place.
7. Rinse end of sewer hose thoroughly with
water and stow.
NOTE:If the hose will not collapse while storing,
open the hose end valve (handle) to
release air trapped inside the hose.
8. It is advisable to add an odor control chemical
to the sewage holding tank. These chemicals
are available at most RV supply stores.
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.

usual manner at approved sewage disposal
station.
2. Leave black water dump valve open while
