A tank leaking from the tank itself, not a fitting or valve, means the tank has failed internally and can’t be repaired. Age is the other main factor: a tank-style unit generally lasts eight to twelve years, and once it’s past that mark, sinking money into a repair on a unit that’s likely to fail again soon rarely makes sense. If the household has grown, or the current tank has always run out of hot water too quickly, replacement is also the point to correct the sizing rather than repeat the same undersized unit.
We’ll tell you honestly when a repair is the better call. Replacement gets recommended when the numbers actually favor it, not by default, and we’ll walk through gas versus electric, tank versus tankless, and correct sizing for your household before any unit gets ordered, so the one that goes in is the right one rather than whatever happened to be on the truck.
