How do I know if my anode rod is bad?
The only definitive way is to pull it out and visually inspect it. If more than six inches of the core wire is exposed, it's time for a new one.

Anode Rod Replacement
Every traditional water heater contains a sacrificial anode rod. Its sole purpose is to attract corrosive elements in the water so they eat the rod instead of the steel tank walls. Once the rod is completely consumed, the water will aggressively attack your tank, leading to a rupture. Replacing a depleted rod is the cheapest insurance for your heater.
When this service makes sense
We shut off the water and power, relieve the tank pressure, and use specialized tools to break the factory seal on the top-mounted anode rod. We extract the old rod to show you its condition. If it is heavily pitted or stripped to the core wire, we drop in a fresh magnesium or aluminum rod.
- Water smells vaguely of sulfur or rotten eggs
- The heater is more than four years old and has never been checked
- You use a water softener (which can accelerate anode depletion)
- Tap water has a slightly metallic or bitter taste

What to expect
The service is quick and non-invasive. You gain peace of mind knowing the internal lining of your expensive water heater is actively protected against rust for another few years.

Common questions
Does having a water softener affect the anode rod?
Yes. Softened water increases the electrical conductivity inside the tank, which causes the anode rod to sacrifice itself much faster.
Why does my hot water smell like rotten eggs?
Certain bacteria react with magnesium anode rods to produce hydrogen sulfide gas. Switching to an aluminum or powered anode rod usually eliminates this odor.
