Why does my hot water smell like rotten eggs?
Find answers to common water heater questions from CANRO Heating & Cooling. Our licensed technicians answer frequently asked questions about water heater problems, maintenance, and repairs for Greater Vancouver homeowners.
Expert Answer from CANRO
A rotten egg smell in hot water is usually caused by sulfur bacteria reacting with the magnesium anode rod inside the tank. Replacing the magnesium anode with an aluminum/zinc alloy rod often resolves the issue. Flushing the tank and chlorinating the system may also help. If only hot water smells, the water heater is the source.
