Electric water heaters run differently from gas ones, and in a county where most homes are on electric heat, a contractor diagnosing a failed unit looks at the elements and thermostats first. Electricity heats more occupied homes in Wayne County, Missouri than any other fuel, at 54.5% (2020-2024 ACS 5-year). Sediment buildup accelerates element failure in electric tanks because the element cycles against the buildup directly, rather than through water the way a gas burner heats from below. A contractor here pulls the lower element before quoting a full replacement, because that component fails first and most often in electric units running under a standing household load.

Water heaters in a house this old are rarely on their original equipment, which means the system a contractor opens may have been pieced together across several replacement cycles. Parts from one generation do not always match the fittings or the control wiring carried over from another. Half the homes in Wayne County, Missouri were built in 1980 or earlier (2020-2024 ACS 5-year). When a contractor pulls the access panel, what they find determines whether a straightforward repair is possible or whether a substitute part has to be sourced, modified, or priced against a full replacement. That gap between what the house was built to hold and what is running in it now is where the repair decision actually lives.
The Parts of a Water Heater a Contractor Checks First

The tank is the piece a homeowner notices: a tall cylinder standing in the basement, utility closet, or garage. Inside it, a burner or heating element warms the stored water, and a thermostat controls the target temperature. When water runs cold or inconsistently hot, the thermostat or heating element is where a contractor looks first.
A pressure relief valve sits on the side of the tank and opens if pressure builds too high inside. The anode rod runs down through the tank's interior and slows corrosion of the tank walls. Cold water enters through a dip tube at the top and travels to the bottom before it heats, so a broken dip tube sends cold water straight to the tap.

Extreme weather puts real strain on water heaters, forcing them to recover faster and work harder to hold temperature. How much of that pressure your unit faces depends on what the local climate actually delivers.
