Close both the black and gray tanks while in a CG. Have your sewer hose hooked up. When black is full open it turn you black tank flush on. After it has run for awhile turn off the flush. Let the black tank finish draining. Close the black. Open gray and let it drain. That will help rinse the hose. Once drained close the gray.
