Corroded anode rod leading to tank failure
Why it happens here
The local water supply in Lago Mar is hard on anode rods, and builder-grade tanks often have a thin rod that wears out in five or six years. Once the rod is gone, the tank rusts from the inside.
Our approach
We replace the anode rod during every water heater replacement and recommend checking it annually. If your tank is still under warranty, we can sometimes replace just the rod, but if the tank is corroded, we swap the whole unit.
