Inside every tank water heater hangs a magnesium or aluminum rod whose entire job is to corrode so the steel tank doesn't. It's called a sacrificial anode rod — and in DeSoto's aggressive hard water, it sacrifices itself fast. Once it's gone, the tank wall is next, and a leaking tank is only a matter of time.
Anode replacement is the highest-value maintenance a tank owner can buy: a $200–$400 service that can add years to a tank's life. We check rod condition with a proper inspection, install the right alloy and length for your unit, and can combine it with a flush in the same visit.
Active leak, no hot water, or gas smell — don't wait. Call Emergency Line
Inspect: we extract and measure the existing rod — diameter tells us how much life is left.
Select: magnesium, aluminum, or powered anode matched to your water chemistry and odor issues.
Install: new rod torqued to spec with thread sealant; tank flushed while we're in there.
Storm-season note: we recommend anode checks as part of pre-storm-season maintenance. A tank with a healthy anode and flushed sediment handles the thermal stress of post-storm recovery cycles far better than a neglected one.
| Service | Typical Range |
|---|---|
| Anode inspection / service call | $89–$149 |
| Anode rod replacement | $200–$400 |
| Anode + full tank flush combo | $200–$400 |

Every 3–5 years in our hard water — sooner for softened water, which is even more aggressive to anodes. Annual checks after year three are smart.
Often, yes — switching from magnesium to aluminum/zinc alloy usually kills the rotten-egg odor. Persistent odor may need a powered anode or chlorination.
No. Once the tank shell leaks, the corrosion has won. Anodes prevent leaks; they can't reverse a failed tank.
An electronic rod that never depletes and fights odor aggressively. Higher upfront cost, zero replacement cycle — ideal for problem water.
