water tank each time the black water holding
tank is dumped or as needed:
1. Dump the black water tank and leave the
black tank drain valve open.
2. Connect a garden hose from the water
supply source to the “black tank rinse.”
3. With the water source turned ON, flush
the black water holding tank until the
water running out of the black tank drain
valve is clear (not discolored or cloudy).
4. Disconnect the garden hose and close the
“black tank drain” valve.
5. Fasten the sewer hose housing dust cap
back on the “black tank rinse.”
Do not leave any hose (water supply)
connected to the black tank rinse when it is
not in use.
The black tank drain valve must be OPEN
any time there is a hose (water supply)
connected to the black tank rinse.
