We had an issue with a sulfur smell in our hot water. Turns out it was caused by a bacteria that fed on the magnesium anode rod in the water heater. It was not harmful, just created the smell.
I removed the anode, flushed the system with bleach and installed an aluminum anode instead of the magnesium one. Smell went away.
