Gas-fired water heaters run their burners, igniters, and thermocouples every day of the year, not just through a heating season, so the combustion side accumulates wear steadily. Utility gas heats more occupied homes in Tompkins County, New York than any other fuel, at 46.3% (2020-2024 ACS 5-year). A contractor repairing a gas water heater in this county checks the gas valve, the thermocouple, and the burner assembly first, because those are the parts the fuel demands the most from. Sediment in the tank and anode rod condition come next.
Water heater repairs in housing this old tend to uncover more than the failed part itself. Half the homes in Tompkins County, New York were built in 1974 or earlier (2020-2024 ACS 5-year). Plumbing that has been in service that long accumulates sediment, develops corrosion at fittings, and runs on supply lines that were last touched decades before the current unit was installed. A contractor opening a tank here is often looking at connections and shutoffs that are overdue on their own, separate from whatever triggered the call. Parts for the unit may still be available, but the surrounding plumbing can extend the scope of the job before the repair is finished.
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 closet. It holds and heats the water. When sediment builds up inside it or the lining deteriorates, the tank itself is what a contractor examines. The dip tube, which runs down into that tank, directs cold incoming water to the bottom so it heats evenly, and a failed one is a frequent cause of lukewarm water at the tap.
The anode rod hangs inside the tank and draws corrosion to itself, protecting the tank walls. When it is spent, the tank starts to corrode instead. The pressure relief valve sits on the side or top of the tank and is a safety device a contractor always checks. The burner assembly or heating element, depending on whether the unit runs on gas or electricity, sits at the base or inside the tank and is what a contractor looks at when there is no heat at all.
The drawing shows a representative layout, and a licensed contractor determines which components apply to the specific unit and setup in your home.

Extreme weather puts strain on water heaters: temperature swings, power surges, and hard freezes all accelerate wear on equipment that runs year-round. How much of that stress a system absorbs depends on what the local climate actually delivers.
