The smell can be a result of valves left open and waste being allowed to dry out.

If it breaks or gets blocked or stuck, you'll need to find someone to clean or replace the pipes.Mar 7, 2021,
There could be odor-causing bacteria feeding on debris in your pipes. This process will give off a foul-smelling hydrogen sulfide gas, which smells like sewage or rotten eggs. Also, mold grows where it's warm and wet — and mold growth on the debris causing a drain clog can also cause a bad smell.

Start by pouring ¼ cup of baking soda down the drain, and then leave it for about 10 minutes. Then, follow it with one cup of vinegar. Let the mixture fizzle and work for a few minutes, and then finish by turning on the water and running the disposal to clear out any leftover food waste.
A common cause of why your RV smells like rotten eggs is that anaerobic bacteria in your RV water heater tank reacts with the sulfur and magnesium of the anode rod. This interaction produces hydrogen sulfide gas – your rotten egg odor.Aug 22, 2021
