Gas water heaters run every day of the year, not just through a heating season, so the burner, the thermocouple, and the ignition system accumulate wear steadily and without interruption. Utility gas heats more occupied homes in Asotin County, Washington than any other fuel, at 52.9% (2020-2024 ACS 5-year). Contractors diagnosing a failed or underperforming unit here work through those combustion components first, because the venting path and gas valve are where faults concentrate in a home that depends on utility gas. A corroded thermocouple or a partially blocked burner orifice will cause intermittent heating long before the tank itself fails, and catching it early keeps the repair on the smaller side of the bill.

A water heater sitting in a house this old has usually been replaced at least once, and the plumbing and pressure relief infrastructure around it was fitted and refitted by whoever came before. Half the homes in Asotin County, Washington were built in 1976 or earlier (2020-2024 ACS 5-year). When a contractor opens the tank or pulls the elements, what they find reflects that layered history: sediment loads that accumulated across successive units, corroded fittings from connections made under different hands, and anode rods that were never swapped on schedule. The parts question matters here too, because the system a contractor is repairing may be mid-cycle in a house that has already worn out one generation of equipment.
The Parts of a Water Heater a Contractor Checks During a Repair

The tank is the piece most homeowners recognize: a tall cylinder that sits in a utility closet, basement, or garage and holds a supply of hot water ready for use. When it fails, symptoms range from no hot water at all to water that smells off or pools on the floor around the base.
The burner assembly or heating element sits inside or beneath the tank and is what actually raises the water temperature. A thermostat mounted on the tank tells that component when to fire. The pressure relief valve, positioned on the side or top, is a safety device a contractor checks for signs of leaking or corrosion.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to the water heater in your home.
