RV Water Tank Problems

The reason why does your fresh water tank or even the cold water in an RV smells like rotten eggs is that the issue may be in your main water system. This usually happens when water is stored for long periods.

When the tank is not cleaned regularly, the bacteria grow and spread through the RV’s freshwater tank, making the camper water smell like rotten eggs. Besides this, dirty plumbing or hoses also cause the camper RV water to stink.

RV Water Heater

When a hot water heater smells like rotten eggs, it is usually because the anode inside the heater is reacting with the bacteria, which causes an unpleasant odor. This is why many people ask why my RV hot water tank smells like rotten eggs or sulfur. While the cold water seems fine.

So, if only the RV hot water stinks, but cold water doesn’t, know that the water heater is the main source of the smell. In some cases, an RV fridge smells like rotten eggs due to issues with the cooling unit, a propane leak, or overcharged batteries, which can be mistaken for a water-related smell.

Waste Tank Odor

Sometimes, the rotten egg smell in the camper is not coming from your fresh water but the waste tank. The grey tank holds sink and shower water. Similarly, the black tank stores toilet water. Both can produce a strong odor if not cleaned or maintained regularly. While doing rv remodeling, keep plumbing and water sanitation in mind.

So, if the RV’s fresh water lines, sink, black or grey tank smells like sewerage or rotten eggs, waste buildup is likely causing the odor. Moreover, a rotten egg smell from the RV toilet or sink can occur if the gases from waste travel back through the plumbing system.
