Section 8: Plumbing System
Waste (grey) holding tank preparation
No special preparation is required, however, placing a small quantity of chemicals into this
tank, such as baking soda or an approved RV chemical, will reduce odors from food particles
in the system.
Cleaning and Maintenance
The toilet should be cleaned regularly for maximum sanitation and operational efficiency.
Use only RV approved chemicals. Do not use chlorine (undiluted) or caustic chemicals,
such as laundry bleach or drain opening types, in the toilet system. These products damage
the seals in toilets and dump valves.
Black Tank Flush (if so equipped)
The black tank flush inlet is typically located on the utility center pan
-
el. The location may vary depending on your model. The inlet color
may be either white or black. Attach a garden hose connected to a
pressurized fresh water source to the black tank flush inlet. The water
goes directly into the black water holding tank sprayer connection,
allowing you to remove debris and preventing accumulation. There
is a check valve in the plumbing lines to prevent back flow.Flush the
black water tank each time the grey and black water holding tanks are
dumped or as needed.
1. Dump the black water tank (see Gray Tank Drain & Black Tank
Drain) and leave the black tank drain valve open.
2. Connect a garden hose from the water supply source to the black
tank flush.
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. Fasten the sewer hose
housing dust cap back on the tank flush inlet.
Tank Flush Inlet
Do not use the same hose to fill your fresh (potable) water tank that is used for
the black tank flush.
The black tank drain valve must be OPEN any time there is a hose (water
supply) connected to the black tank flush.
Do not leave any hose (water supply) connected to the black tank flush
when it is not in use.
