NOTE:
Close the grey water valve 24 hours
prior to departing to allow the tank to
fill with liquid to help in the dumping
process.
Draining the Tanks
The waste holding tanks should be full or
nearly full prior to draining to help evacuate
the tanks more efficiently.
To Drain the Tanks:
1. Attach sewer hose to termination
drain and shore facility.
2. Prepare to dump the solid waste
(black) tank first. Close the liquid
waste drain (grey) valve.
3. Fill the grey tank to at least 50%
by running water in the shower or
sinks. Use the tank monitor panel to
observe tank fluid levels. When the
grey tank is 50% full, stop filling the
tank.
4. Secure the drain hose to prevent
movement. Open the solid waste
drain (black) valve. Allow the black
tank to drain.
5. Flush the black tank using the
Tank Flush fitting in the water
service center. Flush the tank for
approximately 2-3 minutes.
6. When complete, close the black water
valve.
7. Open the grey water valve. The water
in the grey tank will flush remaining
solids from the sewer hose. With
the grey water valve open, run two
gallons of water down any drain
to flush grey tank. The grey valve
remains open until the next drain
cycle, or time of departure.
Preparing for Travel:
1. Close solid waste (black) and liquid
waste (grey) valves.
2. Undo restraining devices from the
sewer hose. Disconnect the sewer
hose from the termination drain by
rotating the fitting counterclockwise
90º.
3. Raise the sewer hose and using hand
over hand method working the sewer
hose towards the shore fitting.
4. Rinse the sewer hose with outside
facility and repeat the hose drain
process.
5. Remove the sewer hose from shore
fitting.
6. Store the sewer hose.
7. Secure the termination cap to the
termination drain (required by law in
some states).
8. If desired, add chemicals to the tanks
to control odor. Follow the directions
given by the manufacturer of the
chemical.
NOTE:
Dump the black tank and grey tank
before driving.
NOTE:
Always empty the tanks before
traveling.
Drain Traps & Auto Vents
A “P-trap” and auto vent are located at each
sink and shower drain to prevent holding tank
odor from entering the recreational vehicle.
These P-traps are usually within 54” of a vent
tee. These traps must have water in them to
block odors.
During storage,
water can evaporate
and allow odor into
recreational vehicle.
If odor is detected,
run water into sinks,
shower drain and
washer (if equipped)
traps.
The auto vent is to assist in the flow of water
in the drain lines by enabling a smooth flow of
water in the drain without creating a vacuum.
If the auto vent is stuck in the open position,
grey tank odors may enter the recreational
vehicle. Auto vents double as clean outs in
case the line has to be “snaked” out.
NOTE:
During cold weather antifreeze must
be added to the drain traps.
