A gas water heater here runs every day of the year, not just through winter. Utility gas heats more occupied homes in Blaine County, Montana than any other fuel, at 40.0% (2020-2024 ACS 5-year). That share of gas-heated homes means contractors working water heater repairs in this county spend most of their time on burner components, thermocouples, and gas valves rather than on electric elements or heat pump coils. A part that is starting to fail rarely announces itself until demand peaks, and in a home that has burned gas this long, the burner orifice and igniter deserve a close look before anything else gets priced.
Sediment accumulation and anode rod corrosion are what a contractor opens a tank and finds in this county, often in systems that have been working against mineral-heavy water for far longer than the equipment was rated to last. Half the homes in Blaine County, Montana were built in 1972 or earlier (2020-2024 ACS 5-year). A house that old was plumbed once and largely left alone, which means the tank, the supply lines, and the pressure relief valve have all had the same extended run against hard water. When a repair call comes in, the presenting symptom is rarely the whole story: a contractor flushing sediment from one component frequently finds the next component already compromised.
The Parts of a Water Heater a Contractor Checks First
The tank is the center of the system, sitting in a utility room, basement, or closet, and its job is to hold water at a set temperature so hot water is ready on demand. The burner assembly or heating element sits at or near the bottom of the tank and is the first place a contractor looks when the water stops heating.
The pressure relief valve mounts on the side of the tank and releases if pressure builds beyond a safe point. The anode rod hangs inside the tank to slow corrosion, the thermostat controls the target temperature, and the dip tube directs cold incoming water to the bottom so it heats before it rises to the outlet.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific unit and setup in your home.

Extreme weather puts real strain on water heaters, forcing them to work harder and recover faster than they were sized to do under mild conditions. How much of that strain a unit carries over time is a local question, and the record below reflects what the climate in this county has actually delivered.
