HOWTO: Waste Water Dumping
107

If possible, you want to dump the tanks after driving as the movement of the vehicle will have sloshed the water in
the tanks, loosening any solids.
Make sure the tanks are as full as possible before dumping - you may wish to use a hose or bucket to add water to
the black water tank through the toilet if it is less than 1/2 full.
You should dump the black tank first, then the gray tank. The water in the gray tank is considerably cleaner, and will
rinse any remaining solids from the hose and the macerator. You should dump both tanks in sequence if possible.

• Open the compartment doors or drawer behind the driver. This will expose the green waste water discharge hose and
controls.
Depending on your model, your hose and dump valve location may look a bit different. Take the time to identify all of
the components before you start.
