Tank Leak Repair
Leaking conventional tank? We pinpoint whether it's a fitting, valve, or the tank itself — and repair what's repairable.
Learn More →Inside every tank water heater is a metal rod most homeowners never see — the sacrificial anode rod — and it is the only thing standing between your hot water and a rusted-out tank. It works by corroding in place of the steel tank: a slow, deliberate sacrifice that buys your heater years of extra life.
The catch? Once the rod is fully consumed, the tank starts corroding instead — and that clock runs faster than most people think. In Medford-area water, an anode rod typically lasts 3–5 years, while the tank it's protecting is expected to last 8–12. Replacing the rod on schedule is the single highest-value maintenance a tank heater can get.
Rotten-egg or sulfur smell in hot water (but not cold) is the classic sign — it means the rod is depleted and bacteria are reacting with the remaining metal. Rusty or discolored hot water, a tank that's suddenly noisier, or a heater approaching the 5-year mark without ever having the rod checked are all strong indicators.
Local water chemistry matters. Mineral content and water softeners both accelerate anode consumption — softened water is particularly aggressive, and can cut rod life nearly in half. If you have a softener and an aging heater, your anode rod deserves attention sooner, not later. Winter adds its own stress: heavier burner use means more thermal cycling on an already-thinning rod.
We'll recommend the right rod for your situation. Standard magnesium rods offer the best protection in most Medford homes; aluminum-zinc rods are the go-to fix for sulfur smells, since they discourage the bacteria reaction that causes the odor. For hard-to-access installations, we carry flexible segmented rods that bend into tight spaces.

In most cases, yes — especially with an aluminum-zinc rod, which resists the bacteria reaction behind the odor. If the smell persists, we'll investigate further.
Not necessarily. If the tank isn't leaking, a fresh rod can still slow further corrosion. But at that age, we'll inspect honestly — sometimes the money is better put toward a planned replacement.
An impressed-current (powered) rod uses a small electrical current instead of sacrificial metal, so it never depletes. It's a premium option worth considering for expensive tanks or aggressive water conditions.
