Electric water heaters run every day of the year, and the heating elements inside them degrade steadily under that constant draw. Electricity heats more occupied homes in Horry County, South Carolina than any other fuel, at 86.4% (2020-2024 ACS 5-year). A contractor diagnosing a failed or sluggish water heater here checks the elements first, then the thermostats, then the anode rod, because that is the order in which those components wear under a purely electric load. Sediment buildup on an electric element shortens its life faster than on a gas burner, and in a county where gas is rarely an option, a replacement unit is electric too, which makes the wiring, breaker size, and connection quality part of the repair scope.
Plumbing assemblies in houses this age tend to carry evidence of more than one repair generation: corroded fittings where different contractors stopped, replacement lines that do not match the original routing, and pressure relief valves that were swapped without updating the discharge path. Half the homes in Horry County, South Carolina were built in 1999 or earlier (2020-2024 ACS 5-year). That history matters when a water heater repair is being scoped, because the failed component a homeowner calls about is often seated inside a larger assembly with its own condition. A contractor who opens the unit and stops there can miss a corroded supply connection or a venting joint that will bring the same homeowner back within a season.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank is what most homeowners recognize: a large insulated cylinder that sits in a utility room, basement, or garage and holds the water supply until a tap calls for it. The burner assembly or heating element sits at the base or interior of the tank and is the first place a contractor looks when hot water stops arriving or arrives inconsistently.
The pressure relief valve mounts directly on the tank and releases if internal pressure climbs too high, making it a safety piece a contractor tests early in any diagnostic visit. The anode rod runs through the tank's interior and slows corrosion from the inside out, and the dip tube directs cold incoming water to the bottom so it does not mix with the heated water sitting near the top.
The drawing shows a general layout of these components, and a licensed contractor determines which of them apply and what condition they are in for the specific unit in your home.

Storm activity puts real stress on water heaters: pressure swings, power interruptions, and temperature fluctuations all push equipment harder than ordinary daily use. How much of that stress a unit carries depends on what the local weather actually delivers, which is why the record for this area belongs in a conversation about repair work.
