Tank
To fill the fresh water holding tank, set the selector to Tank and with hose connected, turn on the
campground water faucet. The fresh water holding tank has overflow hoses. When the tank is full,
water will come out of the overflows on each side of the frame.
Black Tank Flush Connection(s)
There is a separate water inlet connection for the black tank flush. And if your RV has a 2
nd
bathroom,
there is a second connection to flush that black tank.
The black tank flush allows you to run campground water through a sprayer mounted inside the black
tank in order to help clean out the tank.
Safe Practices
It’s a good practice to use a different, clearly marked hose for the black tank flush. Although the routing
of the black tank flush water lines, and the use of a vacuum breaker valve, will help prevent
contamination of the water hose, it’s a good practice to use a different hose to provide additional
protection against contamination in the event of a valve failure. Some owners add an additional check
valve to the Black Tank Flush Inlet to provide further protection against contaminating hoses or the
campground faucet.
Whenever water is running through the Black Tank Flush, you should either have the black tank gate
valve in the open position, or if the gate valve is closed, you should take great care to avoid overfilling
