Why does my hot water smell like rotten eggs?
Make sure you only smell the smell in your water. If you smell a rotten egg smell in the air, you may have a gas leak and everyone should leave your home immediately and call 911. If your hot water smells like rotten eggs, it’s usually caused by hydrogen sulfide gas from bacteria reacting with the anode rod in your water heater. This is common in homes with well water or water that sits unused. Flushing the tank and replacing the anode rod with an aluminum or zinc one often solves the problem. The water is generally safe but unpleasant.
