A contractor called out to repair a water heater in Cobb County has to account for what the system has already been running against. 105 severe weather events were recorded in Cobb County, Georgia between 2015 and 2024. At that rate, severe weather is a standing part of the environment every unit here operates in, and a technician checking a failed heating element or a corroded anode rod has reason to weigh stress load alongside the more obvious suspects. Age and installation quality still drive most failures, but skipping the weather load question in a county with this kind of record produces diagnoses that miss what pushed a marginal component over.
Half the homes in Cobb County, Georgia were built in 1990 or earlier (2020-2024 ACS 5-year). A water heater sitting in a house of that vintage has likely been replaced or patched at least once, and what a contractor finds when the unit is opened reflects that layered history: corroded connections, non-standard fittings, or components that manufacturers stopped producing years ago. That last point is where a repair job can change direction. If the part the system needs is still available, the repair is straightforward. If it has been discontinued, the contractor is pricing a replacement instead, and the homeowner is making a different decision than they expected when they called.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank is the piece a homeowner notices first, a large insulated cylinder that sits in a utility closet, basement, or garage and holds the home's supply of hot water. Attached to it are the pressure relief valve and the drain valve, both mounted directly on the tank body. When a tank repair call comes in, the contractor starts there, looking at whether the tank itself is the source or whether a component on it has failed.
The burner assembly or heating element sits inside or beneath the tank depending on whether the unit runs on gas or electricity, and the thermostat mounts to the outside of the tank and tells the heating source when to fire. A gas unit also has a flue running up through the top to carry exhaust out of the house. The anode rod rides inside the tank and is a common first stop during a repair call because its condition affects the whole tank.
The drawing shows the general layout of a water heater system, and a licensed contractor determines which parts apply to the specific unit and setup in your home.

Extreme weather puts real stress on water heaters, which work harder to recover when temperatures swing and may take physical damage from flooding or power surges. How often that happens here shapes how much wear local units absorb over time.
