What is an RV Sewer Donut?

This is the equipment that goes into the sewer hole at the campground. There may be air gaps if you connect that hole directly to your black water sewer pipe. When those spaces exist, odors escape and make the surrounding environment unpleasant.

When you put the doughnut in the sewer hole and the connection on the waste line, the gaps should be filled, and no more foul odor should escape. These doughnuts are round, made of rubber, and have a tapered end to fit into any waste hole you come across.

The good news is that they are not particularly large or heavy. They are readily stored and contribute nothing to your weight restriction. Many people have them; however, with recent renovations to many campgrounds, they have hardly been used anymore, even though certain states have implemented laws mandating their usage.

The donuts are only required if the sewage connection lacks a threaded fitting. Even if it doesn’t, your connecting elbow or other fittings may force their way into the pipe. We keep a donut on hand in case it is required.
