Ok, What is a Sewer Donut For RV?
A sewer donut is a round rubber device used to seal off the ground sewer connection.
When you do a straight connection between that hole and your black water sewer pipe there can be air gaps. When there are those gaps, the odor, etc., escapes and makes the surrounding area unpleasant.
Once you place the doughnut in the sewer hole and then your connector on the waste line, those gaps are supposed to be sealed and no more foul odor escapes. These doughnuts are round, made of rubber, and have a tapered end so that they will fit into any waste hole you encounter.
