Gas-fired water heaters run their burner, thermocouple, and gas valve hard year-round, not just through a heating season. Utility gas heats more occupied homes in Fallon County, Montana than any other fuel, at 50.9% (2020-2024 ACS 5-year). Because gas is what most homes here burn, a contractor diagnosing a failing water heater starts at the combustion side first: the burner orifice, the thermocouple, and the gas valve are the parts that accumulate the most wear in a gas-dominant household. Sediment buildup in the tank follows, fed by repeated heating cycles. Venting condition matters too, since a blocked or deteriorating flue on a gas unit is a safety issue the contractor checks before anything else.

Half the homes in Fallon County, Montana were built in 1982 or earlier (2020-2024 ACS 5-year). Houses plumbed that long ago were fitted with supply lines, valves, and connections that have been working against hard water for a long time, and what a contractor finds when they open access to a water heater here often extends past the unit itself. Sediment accumulation in older tanks shortens the useful life of a heating element, and corroded fittings around a tank that age can turn a straightforward repair into a broader job once the first connection is disturbed. The parts a contractor orders depend on what the plumbing around the unit actually is, not on what the work order says going in.
The Parts of a Water Heater a Contractor Checks First

The tank is the piece a homeowner notices first, usually standing in a utility room, basement, or garage. It holds and heats the water your household draws on. When something goes wrong, the tank itself, its lining, or the pressure relief valve on its side are among the first things a contractor looks at.
The burner assembly or heating element sits at the base or interior of the tank depending on whether the unit runs on gas or electricity. The thermostat, mounted on the outside of the tank, tells that heating source when to fire. The dip tube runs down through the top of the tank to deliver cold water to the bottom, and the anode rod hangs inside to slow corrosion. Any of these can be the source of a problem.
