Waste Water - Road Bear RV Class C 19-22' Manual

3.8.2. Waste water

The motor home has two separate waste water or holding tanks:
- "grey water" – kitchen and bathroom sinks and shower
- "black water" - toilet
The holding tank drain valves are mostly on the left side of the vehicle. First you
need to attach the sewer hose (located in one of the outside storage
compartments) via the bayonet coupling to the outlet after removing the sewer
outlet cap by a quarter turn. The open end of the sewer hose with the red 90
degree angle piece goes into the sewer pipe at the dump station or campsite.
Then open the valves by pulling the sliding handles out.
Start with the black water valve (larger of the 2 valves) and then the grey water
valve. Once they are both empty close the 2 valves. In case the monitor panel
does not show empty (E) repeat this task otherwise remove sewer hose and
snap the cap back on. Store sewer hose in its place. Add chemicals for the black
tank into the toilet.
In case you stay for a few days at full hookup (incl. sewer) never leave both
valves open. Pull them once a day only or when needed (especially the black
tank). Dry waste makes emptying the tanks very difficult.
Most campgrounds have a dump station. There are also dump stations on some
rest areas and some gas stations, just look out for the following freeway sign:
