Gas water heaters run every day of the year, not just through a heating season, so the burner, the thermocouple, and the gas valve accumulate wear that a repair contractor has to trace back through before they can quote accurately. Utility gas heats more occupied homes in Ravalli County, Montana than any other fuel, at 40.9% (2020-2024 ACS 5-year). That share of the housing stock means contractors here work on gas-fired equipment constantly, and a technician diagnosing a failing unit will check the burner orifice and ignition components first, because those are the parts the fuel type and daily cycling actually wear out.

Sediment builds over decades, and in much of Ravalli County's housing stock, a water heater that is throwing symptoms has usually been doing so quietly for some time before it surfaces. Half the homes in Ravalli County, Montana were built in 1991 or earlier (2020-2024 ACS 5-year). That means a contractor opening a unit here is likely finding mineral buildup at the dip tube, corrosion at the anode rod, and pressure relief hardware that has never been tested, not a single failed part. The repair scope that comes back to a homeowner reflects what the opened tank actually contains, which in stock this age runs longer than the initial call suggested.
The Parts of a Water Heater a Contractor Checks First

The tank itself is the piece a homeowner notices first, usually standing in a utility room, basement, or garage. It holds and heats the water the house uses. When hot water runs out too fast, takes too long to recover, or arrives discolored, the tank and the burner or heating element inside it are where a contractor starts.
The pressure relief valve sits on the side of the tank and releases if pressure builds beyond a safe point. The anode rod hangs inside the tank and slows corrosion. The inlet and outlet connections at the top move cold water in and hot water out to the rest of the house, and the thermostat controls what temperature the water reaches.
The drawing shows the general layout of a water heater system, and a licensed contractor determines which parts apply to the specific unit and setup in your home.
