Before a contractor can pin down why a water heater failed, they have to establish what the unit has actually been carrying. 122 severe weather events were recorded in St. Joseph County, Michigan between 2015 and 2024. At that rate, severe weather is a genuine part of the operating picture, but it rarely sits at the top of a repair diagnosis on its own. Sediment buildup, anode rod condition, and whether the original installation was sized and set correctly tend to account for most failures a contractor finds here. Weather load is part of the history, not usually the explanation.
Water heaters installed in houses of this vintage often take parts that manufacturers have discontinued or moved to special-order status. Half the homes in St. Joseph County, Michigan were built in 1970 or earlier (2020-2024 ACS 5-year). A contractor opening a unit in a house this old has to confirm what is still available before the repair scope is set, because a straightforward fix can shift into a sourcing problem the moment the failed component turns out to be obsolete. That changes what the homeowner is deciding: a repair whose parts exist is one job, and a repair whose parts do not is a different one.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank is the piece most homeowners recognize, a large insulated cylinder that sits in the basement, utility closet, or garage and holds the water supply at a set temperature. When something is wrong with the tank itself, the signs tend to be visible: corrosion, pooling water, or a vessel that simply cannot hold heat anymore.
The burner assembly or heating element sits at the base or inside the tank depending on whether the unit runs on gas or electricity, and the thermostat attaches directly to the tank to read and regulate temperature. The pressure relief valve mounts on the side and opens automatically if pressure climbs too high. A contractor also checks the anode rod, a metal shaft suspended inside the tank whose job is to draw corrosion away from the tank walls.
The drawing shows a general layout of a water heater and its components, and a licensed contractor determines what applies to the specific unit and installation in your home.

Hard weather puts water heaters under pressure: recovery cycles run longer, sediment stirs, and components that were marginal start to fail. How often that stress hits St. Joseph County shapes how much repair work the equipment here actually needs.
