Black Water Waste Tank Rinse
The motorhome is equipped with a black water
waste tank flushing system to improve draining
and to reduce odor. To flush the tank, follow
these steps:
1. Remove the protective cap, and connect
the city water supply hose to the connector
(3) located in the exterior utility center.
2. Open the black water tank dump valve (1).
NOTICE
Always open the black water tank dump
valve before turning on the water supply.
3. Turn on the city water supply to thoroughly
flush the system.
4. Turn off the city water supply, disconnect
the city water supply hose, and install the
protective cap on the connector (3).
5. Close the black water tank dump valve (4).
NOTE: The black water tank flush
line incorporates a non-return valve
(5), which prevents black water
contamination of the city water supply
hose. If city water does not flow when
connected as above, the non-return
valve may be defective and require
replacement. The non-return valve is
located behind various wall panels
depending on coach floor plan (see
floor plan for location).
