The hydrogen sulfide gas produced in the tank can cause this smell. What is responsible for the foul odour? Likely the sacrificial rod in your water heater. This article guides you on choosing the best anode rod for smelly water, whether it’s a zinc rod, powered anode rod, or an aluminum zinc anode.
Understanding the Cause of Smelly Water
When your hot water begins to emit a rotten egg smell, it’s typically due to the presence of hydrogen sulfide gas in the water. This gas is produced when sulfate in the water is converted into hydrogen sulfide.
The odor is intensified when the sulfate interacts with the magnesium or aluminum rod, thereby producing more hydrogen sulfide. What is the result? Rotten egg odour water whenever you run your hot water.
Combatting Rotten Egg Odor with the Right Anode Rods
The good news is, you can combat this rotten egg odor by replacing your anode rod. Here’s where different types of rods can come to your rescue:
Aluminum Zinc Anode Rods
An aluminum zinc rod, an aluminum anode rod with a zinc component, can help reduce the rotten egg odor. Zinc, unlike aluminum or magnesium, is not conducive to producing hydrogen sulfide.
Therefore, when you replace the existing rod with an aluminum zinc alloy rod, it helps reduce the hydrogen sulfide gas, thereby mitigating the smell.
Our selection of top-notch aluminum zinc anode rods is a perfect choice if you’re looking to replace your current anode rod.
Powered Anode Rods
A powered anode rod is another excellent solution for smelly water. Unlike the sacrificial anode rods that attract corrosion and gradually deplete over time, a powered rod provides consistent protection without sacrificing itself. It doesn’t react with sulfates in the water, preventing the production of hydrogen sulfide gas.
Browse through our range of high-quality powered anode rods to find the right one for your water heater.
Magnesium Anode Rods
While magnesium anode rods are usually not recommended if your water smells, they do play a crucial role in attracting corrosion, protecting your tank from rust and damage.
If your water supply doesn’t have high sulfate content or if you use a water softener, a magnesium rod can be a good choice for overall protection.

Factors to Consider when Replacing Anode Rods
When choosing the best rod for smelly water, there are several factors to consider.
Water Softener
If you have a water softener installed at your home, you might need to reconsider the type of anode rod you use. Softeners often accelerate the corrosion of magnesium rods, which could exacerbate the rotten egg smell. In this case, a powered anode rod or an aluminum zinc rod could be a better fit.
Local Water Conditions
The composition of your local water supply is another important factor. If your water has high sulfate content, choosing a powered anode rod or aluminum zinc anode can help reduce the hydrogen sulfide production, ultimately eliminating the rotten egg odor.
Conclusion: Choosing the Best Anode Rod for Smelly Water
A stinky rotten egg odor in your hot water is both unpleasant and unnerving. But with the right anode, you can solve this issue efficiently.
Be it an aluminum zinc anode, powered anode, or even a magnesium anode, choosing the correct rod can help eliminate that persistent smell and ensure your water heater lasts longer.
