Troubleshooting guide

2. Waste Water: The motorhome has two holding tanks: one for “gray water”

(rinse water from sinks and showers), and one for “blue water” or “black water”

(from the toilet). In most models, the valves to empty the holding tanks are on the

left side of the vehicle; in most cases in the back. Before you leave, make sure

that these knife valves are closed and that the cap is screwed on. To open the

valves, pull the sliding handles out; to

close the valves, push the handles in.

Emptying the Tanks: To empty the

tanks, screw the cap off the opening

and attach the dump hose to it.

Connect the other end of the hose to the hole or attachment at the dumping

station. Then, pull the black water valve out. This is the larger (3 ½ “) of the

two valves. The smaller (2”) one is for gray water. After you have emptied the

black water, leave the valve open, then pull valve for the gray water out.
