A water heater running on propane works every day, not just through a heating season, and the burner, thermocouple, and gas valve accumulate wear on a continuous cycle. Bottled, tank or LP gas heats more occupied homes in McPherson County, South Dakota than any other fuel, at 39.7% (2020-2024 ACS 5-year). That fuel mix means most repair calls involve combustion components rather than electrical ones, and a contractor arriving at a propane-fired unit checks the burner orifice and ignition system before touching anything else. Sediment in the tank and venting condition come next, because LP combustion is sensitive to both.
Water heaters in houses of this vintage have often been replaced once or twice already, and each replacement brought its own parts lineage. Half the homes in McPherson County, South Dakota were built in 1962 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, what decides the repair scope is whether the manufacturer still makes the parts that system takes. If the line has been discontinued, the choice shifts from repair to replacement before the diagnosis is finished.
The Parts of a Water Heater a Contractor Checks During Repair
The tank is the piece most homeowners know by sight, sitting in a utility closet, garage, or basement and holding the supply of heated water the house draws from. The burner assembly or heating element sits at the base of that tank and is where a contractor looks first when water stops getting hot or heats unevenly.
The thermostat controls the target temperature and sits directly on the tank body, while the pressure relief valve mounts to the side as a safety device that releases pressure when it climbs too high. The anode rod runs down through the tank interior, and the dip tube carries cold water in at the top so it reaches the heat source at the bottom.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to the specific unit in your home.

Extreme weather puts real strain on water heaters, forcing them to work harder and wear faster than they would under mild conditions. How much of that pressure your equipment faces depends on what this county actually sees.
