Propane water heaters run on a fuel that burns hotter and at higher pressure than natural gas, which puts steady stress on the burner assembly, the thermocouple, and the flue path. Bottled, tank or LP gas heats more occupied homes in Corson County, South Dakota than any other fuel, at 81.9% (2020-2024 ACS 5-year). A contractor diagnosing a failed unit here checks the orifice sizing, the combustion chamber for soot buildup, and the vent connection before moving to the controls, because those are where propane-related failures show up first. Sediment in the tank is a separate issue and arrives regardless of fuel, but the combustion side is where the repair history in this county concentrates.
Sediment buildup and corroded inlet connections are what a contractor opens to find in much of this county's housing stock, and both follow directly from how long the tanks and supply lines have been running. Half the homes in Corson County, South Dakota were built in 1974 or earlier (2020-2024 ACS 5-year). Fittings and anode rods in houses that old are rarely on any regular service schedule, which means the first inspection is also the first accounting of what has been quietly degrading. The repair scope a contractor quotes depends on that physical condition, not on what the unit's label says.
The Parts of a Water Heater a Contractor Checks First
The tank is the piece most homeowners recognize: a tall cylinder that sits in a utility closet, garage, or basement and holds the water supply until it is needed. When a repair call comes in, the tank itself is one of the first things a contractor looks at, checking for corrosion, sediment buildup along the bottom, and whether the lining is holding.
The burner assembly or heating element sits inside or beneath the tank depending on whether the unit runs on gas or electricity, and the thermostat rides alongside it to read and regulate temperature. The pressure relief valve mounts on the side of the tank and releases if pressure climbs too high. A contractor checks each of these because any one of them can be the source of a no-hot-water call, a leak, or an unusual noise.
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 your specific setup.

Extreme weather puts real stress on water heaters, forcing them to work harder and wear faster than they would in mild conditions. How much of that strain a unit accumulates depends on what the local climate actually delivers, which is why the record for Corson County matters here.
