Why Does My Water Smell Like Rotten Eggs?
The unpleasant “rotten egg” smell in water is usually caused by one of two factors:
- The presence of sulfur bacteria or hydrogen sulfide gas in your plumbing system is common in well water or groundwater and is responsible for the foul odor.
- A chemical reaction in your hot water heater, especially noticeable when using hot water occurs when the magnesium anode rod inside the heater reacts with aluminum or other elements, producing hydrogen sulfide gas.
