Electric water heaters put their entire workload through the heating elements, and in a county where electricity is the overwhelmingly dominant fuel, that is what virtually every contractor opening a failed unit will find waiting for them. Electricity heats more occupied homes in Perry County, Mississippi than any other fuel, at 80.1% (2020-2024 ACS 5-year). Sediment builds on the lower element because it sits at the bottom of the tank, and resistive scale on an element that has been cycling hard for years shortens its life in a way a quick pressure test will not catch. A contractor repairing a unit here checks element resistance and the condition of the anode rod before pricing anything else.
Sediment accumulation inside a tank does not announce itself until a contractor opens the system and checks. Half the homes in Perry County, Mississippi were built in 1993 or earlier (2020-2024 ACS 5-year). In housing stock that old, anode rods are often spent, the sacrificial material gone, and the tank wall beneath it already showing corrosion that a surface inspection would not catch. A repair call here frequently widens in scope once the unit is open, not because the equipment was misread from the outside, but because that generation of water heaters has had the time to develop conditions that only show up on the inside.
The Parts of a Water Heater a Contractor Checks During Repair
The tank is what most homeowners see first, usually standing in a utility closet, basement, or garage. It holds and heats the water supply for the house. The burner assembly or heating element sits at the base or inside the tank and is often where a contractor starts when the unit stops producing hot water.
The thermostat controls the target temperature and can cause complaints ranging from water that is too cool to water that is scalding. The pressure relief valve, mounted on the side or top of the tank, is a safety component a contractor will inspect to confirm it opens and closes as it should. The anode rod runs through the interior of the tank and slows corrosion from the inside out.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to the specific unit and installation in your home.

Weather puts work on water heaters. Every extreme event stresses the equipment, and that stress shows up later as a repair call.
