PLUMBING
2. Push the handle forward to open the hose end
valve, then extend the hose and place the
nozzle into the disposal opening.
NOTE: The 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 valves until the
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 sewage tank valve (black handle)
with a quick pull. Move hose gently about to
dislodge any waste and to ensure complete
drainage. Close the valve as soon as the tank
is empty.
NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the gray tank valve
until the black tank is drained and dump
valve closed to avoid sewage back-up
7-10
into gray tank. Gray water also rinses
any black water solids from the drain
hose.
Holding Tank Valves (Typical)
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.
