Water Heater Repair
A water heater that's leaking at the tank itself, not a fitting, is usually past the point of a simple repair, and letting it sit risks a much bigger mess than the leak alone.
When this becomes an emergency
- Rumbling, popping, or knocking sounds from the tank when it's heating.
- Water pooling at the base of the unit with no other clear source.
- Water that's noticeably discolored or smells metallic coming from the hot tap.
- A tank that's ten or more years old and starting to act up for the first time.
What a pro does
A plumber's first move is figuring out whether the problem is a part that fails independently, like a thermocouple, a heating element, or a pressure relief valve, or the tank itself, since only one of those categories is worth repairing. Rumbling or popping sounds usually trace back to sediment that's settled at the bottom of the tank and hardened over time, which insulates the burner from the water and makes it work harder to reach temperature. That's a maintenance issue, not necessarily a failing tank, and flushing the sediment out sometimes resolves it on its own. Water actually pooling at the base of the tank is a different story entirely, since it almost always means the tank itself has corroded through, and a leaking tank gets replaced rather than repaired. Age factors into that decision too: a ten-year-old tank with a tank leak is a straightforward replacement call, while the same symptom on a two-year-old unit is worth a closer look at whether it's still covered.
