Cold groundwater and long winters wear on your water heater here
Your water heater works harder from October through May, when incoming water runs cold and winter nights average 19°F. The burner or heating element stays on longer to make up the difference, and that extra runtime wears on the thermostat and the heating element itself. You notice it as water that takes longer to warm up, or a tank that runs out of hot water sooner than it used to.
Saginaw County has seen 13 winter storms and 79 damaging wind events over the past ten years, and power loss is common across Michigan. Most gas water heaters with a standing pilot keep working through an outage, but electric water heaters and gas models with electronic ignition go down until power returns. If yours doesn't come back on by itself once the power is restored, that points to a problem worth having looked at.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common reason is that the tank itself has rusted through from the inside and is starting to fail. Sediment builds up at the bottom of the tank over years and corrodes the steel until it gives way. Water can also drip from the bottom if the drain valve is loose or a fitting above it is leaking and running down the side. A contractor can tell the difference quickly, but if the tank itself is cracked, the unit needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer telling the gas valve that the pilot is lit, so the valve shuts off the gas. A weak or dirty pilot flame can also fail to heat the thermocouple enough to keep it working. Sometimes a draft from a vent or nearby door blows the flame out before it can do its job. A contractor can test the thermocouple and pilot assembly and replace whichever part is bad.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the unit. Common repairs include cleaning mineral scale out of the heat exchanger, replacing an igniter or flow sensor, and clearing a blocked vent. If the heat exchanger itself has cracked, replacement is usually the better option. A contractor can diagnose which one you are dealing with.
