We have just come back from being on the road for 6 weeks. Although we have emptied the black tank regularly it has not really been washed out. This past week we were not able to empty the tank for 7 days. The lights showed that the tank was 3/4 full. The smell from the toilet on the last 2 days was terrible. Has anyone had a similar problem? If so, any ideas why this should happen.
I have also been told that I should use Bio washing liquid in the tank instead of the "blue biscuits" Has anyone ever tried it?
