SECTION 7 –
PLUMBING
NOTE: The sewage drain outlet swivels
downward 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.
2. Push the handle forward to open the sewage
drain hose end valve, then extend the hose and
place the nozzle into the disposal opening.
NOTE: The sewage drain hose end valve
(handle) must be opened before pulling
the hose to the disposal opening. If the
valve is closed, a vacuum will develop
and prevent the hose from expanding
fully.
Do not open holding tank waste valves
until the sewage drain hose end valve is
open. If you open the dump valve before
the hose valve, the hose will fill with
sewage water and become difficult to
move or could become clogged.
3. Open the Black Waste Tank Drain Valve with
a quick pull. Move the sewage drain hose
gently about to dislodge any waste and to
ensure complete drainage. Close the Black
Waste Tank Drain Valve as soon as the tank is
empty.
NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste Tank
Drain Valve(s) until the black tank is
drained and Black Waste Tank Drain
Valve closed to avoid sewage back-up
into gray tank(s). Gray water also rinses
any black water solids from the sewage
drain hose.
