Water / Plumbing System

Dumping Holding Tanks

To dump the holding tanks
1. Connect the sewer hose (1) to the tank outlet located
on the rear driver's side underbody. The sewer hose
is stored in driver's side rear exterior compartment
(2).
2. Pull out the black tank (3) and grey water tank (4) dump
valve handles in turn. When dumping is complete,
push the handles in.

Black Water Waste Tank Rinse

The Motorhome is equipped with a black water waste
tank flushing system to aid in draining the tank and to
remove build-up of odor. To flush the tank:
1. Remove the protective cap and connect the city water
supply hose to the connector (5) located in driver's
side rear utility compartment.
2. Open the black water tank dump valve (3).
3. Turn on the city water supply, flushing the system
thoroughly.
4. Turn off the city water supply, disconnect the city water
supply hose and install the protective cap.
5. Close the black water tank dump valve.
IMPORTANT
Always open the black water tank dump valve before
turning on the water supply.
NOTE: The black water tank flush line incorporates
a non-return valve 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 (6) is located
behind the soap tray in the shower cubicle.
