What Does It Mean When Your Water Heater Smells and How to Fix It.
At Parts4WaterHeaters, we the essential role a properly functioning water heater plays in a comfortable and efficient home. Unusual smells coming from your water heater can indicate problems that compromise the performance of this critical piece of equipment. That is why understanding and addressing the root cause of these odors is crucial for both the safety of your household and the longevity of your water heater. In this blog post, we'll explore the common reasons behind why your water heater smells and highlight replacement parts and procedures involved with resolving these issues effectively.
Common Causes of Water Heater Smells
1. Rotten Egg Smell
The most common odor associated with water heaters is a rotten egg smell, which is usually indicative of hydrogen sulfide gas. This unpleasant scent is typically caused by bacteria reacting with a corroded magnesium or aluminum anode rod inside your water heater. When these bacteria thrive in the warm, stagnant water, they produce hydrogen sulfide gas, resulting in that distinctive smell.
Solution: To address this issue, replacing the worn magnesium or aluminum anode rod with a new one, or one made of an alternative material can be highly effective. For example, zinc and aluminum/zinc alloy rods are less likely to support bacterial growth. At Parts4WaterHeaters, we offer a wide range of anode rods, comprised of various materials, that are designed to combat this specific problem. Additionally, flushing your water heater and using a hydrogen peroxide treatment can help eliminate the bacteria causing the smell.
2. Garlic or Sulfur Smell
A garlic or sulfur smell can be another sign of bacterial contamination, but it might also indicate a natural gas leak. If you suspect a gas leak, it's crucial to act quickly.
Solution: If you smell garlic or sulfur, first check for a gas leak by turning off the gas supply and contacting your gas company immediately. If the smell is not related to gas, you can follow similar steps as for the rotten egg smell by flushing the tank and swapping out the anode rod with a quality replacement.
3. Burnt Plastic or Rubber Smell
A burnt plastic or rubber smell often points to an electrical issue within the water heater. Common electrical issues include damaged wiring and overheated components. For example, faulty thermostats can cause heating elements to overwork and produce that scorching odor.
Solution: Turn off the power to your water heater and inspect the wiring and connections for any signs of damage or overheating. If you're not comfortable performing this inspection yourself, it's best to call a professional electrician to handle the issue safely. At Parts4WaterHeaters, we stock a variety of electrical components, including thermostats and heating elements to help you make safe and effective repairs.
4. Moldy or Musty Smell
If your water heater emits a moldy or musty smell, it could be due to a buildup of sediment and organic matter in the tank, creating a breeding ground for mold and mildew.
Solution: Regular maintenance is key to preventing mold and mildew. Flush your water heater tank at least once a year to remove any sediment buildup. Additionally, installing a water softener can help reduce the amount of minerals in your water, preventing sediment accumulation.

To avoid unpleasant smells from your water heater, regular maintenance and inspections are essential. Here are a few preventative measures you can take, along with the parts you may need:
