Flying Cloud - Airstream

Now pull the auxiliary tank valve handle to drain the gray tank. When dumping,
the main holding tank should be dumped first; then the auxiliary holding tank.
This will help to rinse out the sewer line with auxiliary holding tank water.
Replace the bayonet ring cap prior to traveling.
Notice: Never put wet strength paper towels or tissues in your holding
tank since they won’t dissolve and can “catch” in the mechanism of the
dump valve. Colored toilet tissue is slower to dissolve than white. Most
RV accessory stores offer tissue designed for RVs that will completely
dissolve.
Deodorizers
There are many deodorizers on the market in tablet, liquid and powder form.
These not only combat odor, but also stimulate the bacteria that works to dissolve
the solids in your tank.
Monitor Panel
Check your monitor panel frequently. When the BLACK WATER HOLDING
TANK is completely full, sewage cannot be emptied from the toilet bowl. If the
GRAY WATER HOLDING TANK is overfilled, drain water will “backup” into the
tub and cause an unpleasant cleaning job. Never drain the tanks at any place
Plumbing
other than an approved dumping station.
When Parked and Connected to Sewer Outlet
When you are in a park and connected to a sewer outlet keep the main holding
tank dump valve closed, and empty the tank every few days or whenever
it becomes almost full. ONLY BY SENDING A LARGE VOLUME OF LIQUID
THROUGH THE MAIN HOLDING TANK AT A TIME WILL TOILET PAPER AND
OTHER SOLIDS COMPLETELY WASH AWAY.
This practice will avoid the accumulation of solids in the main holding tank,
which could lead to an unpleasant cleaning job. Should solids accumulate,
close the dump valve; fill the tank about half full with water, then tow the trailer
for a few miles. The turbulence and surging of the water will usually dissolve
the solids into suspension so the tank can be drained. Keep the auxiliary tank
valve open when connected to a sewer outlet.
Draining the tanks as described will protect them from freezing during storage.
When traveling in sub-freezing temperatures use a winterizing solution
designed for RV use. Follow the directions on the container.
