I have a 2004 Arctic Fox 5th wheel Model 275L. The indicator lights for the holding tanks does not register empty when in actuality it is empty. The light indicates full or partially full. I emptied the tanks, but the light still registered that the tank was partially full. That's both the black and grey water tanks. The valve on the black water tank does not close or stop the flow of water completely and when I go to empty the tank, the pipe is full of crappy water.
What do I need to do to fix these problems and what would be involved?
