Most water heaters in this county run on electricity, which puts the heating elements and thermostats under direct wear rather than spreading the load through combustion parts. Electricity heats more occupied homes in Lexington County, South Carolina than any other fuel, at 69.3% (2020-2024 ACS 5-year). When a water heater fails here, a contractor goes straight to the upper and lower elements, the thermostat contacts, and the wiring connections at the junction box, because those are the parts electricity wears out. A unit fed by gas would send a technician toward the burner assembly and the thermocouple instead. Fuel type is not a background detail on a repair quote; it determines which components get pulled and tested first.
Half the homes in Lexington County, South Carolina were built in 1993 or earlier (2020-2024 ACS 5-year). A water heater sitting on original supply lines and in a space that has never been repiped carries a different repair profile than one in newer construction. What a contractor finds when they open the unit and trace back to the connections can include sediment-packed inlets, corroded relief valve seats, and fittings that have never been disturbed. Those conditions change the scope: a repair that looks straightforward from the outside can require addressing the surrounding connections before the unit itself holds pressure again.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank is the piece a homeowner sees first, usually standing in a utility closet, basement, or garage. It holds the water and keeps it at temperature. The burner assembly or heating element sits at the base or inside the tank, and when a repair call comes in, that assembly is where a contractor looks first.
The pressure relief valve mounts on the side of the tank and opens if internal pressure climbs too high. The anode rod runs down through the tank interior and slows corrosion from the inside out. The dip tube, inlet and outlet connections, and the thermostat round out what a contractor works through when tracing a fault.
The drawing shows the general layout of a water heater system, and a licensed contractor determines what applies to the specific unit and installation in your home.

Extreme weather puts real stress on water heaters, which work harder to recover when conditions outside swing hard in either direction. How often that happens in Lexington County shapes how much wear local units accumulate and how often repair needs come up.
