St. Joseph County puts a water heater to work most of the year
From October through May, eight months a year, your water heater is heating incoming water that starts out cold, sometimes very cold on nights that average 20°F. It runs longer and more often to make up the difference, and that extra run time wears on the heating element and the thermostat that controls it.
The county has also logged 12 winter storms and 159 damaging wind events over the past ten years, and statewide, 17% of households lost power for a day or more in 2024. When power drops, an electric water heater stops heating until it is back, and a gas water heater with an electronic ignition may need to be relit. You will notice it fastest as water that will not get hot, or takes far longer than it used to.

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?
- Most often the tank itself has rusted through and is cracked from the inside. Water heaters don't repair a leaking tank, because once the steel gives way it only gets worse. It could also be a loose drain valve or a fitting that's just leaking under the tank rather than from it, which a contractor can check in a few minutes. If the tank is the source, the water heater needs to be replaced, not patched.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the flame is lit. When it wears out it can't sense the pilot anymore, so the valve shuts the gas off as a safety measure. A dirty pilot orifice or a draft blowing out the flame can cause the same thing. A contractor can test the thermocouple and replace it, which usually solves it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger is common, especially in areas with hard water, and it's cleared by flushing the system. Igniter failures, sensor faults and blocked vents are also things a contractor can diagnose and fix without replacing the unit. Replacement usually only comes up when the heat exchanger itself has failed.
