Cold groundwater and power outages both hit your water heater here
Winter nights in Marion County average 17°F from December through February, and that cold reaches the water main before it reaches your tap. Your water heater has to work harder to bring that colder water up to temperature, and it does this for eight months of the year, October through May. That extra runtime wears on the heating element in an electric unit and the burner assembly in a gas one.
The county has seen 20 winter storms and 79 damaging wind events over the past ten years, and storms like that knock out power. In Iowa, 15% of households lost power for 24 hours or more in 2024. Most water heaters come back on by themselves once power returns, but a unit that was already struggling can fail to recover, and you find out when the water runs cold.

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 failing. Water heater tanks corrode from the inside out over years of use, and once a hole forms, the leak has no fix, since the tank has to be replaced. A leak from the bottom can also come from a loose drain valve or a fitting that has worked its way loose, and a contractor can check those before writing off the tank. If the tank is the source, water pooling underneath it is the sign.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple or flame sensor is usually the reason. That part senses the pilot flame and signals the gas valve to stay open. When it's dirty or worn out, it reads no flame even when one is lit, and the gas valve shuts off. A weak pilot flame, a clogged pilot tube, or a draft near the burner can also cause this. A contractor can test the thermocouple and clean or replace it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is common and can be flushed out, and parts like the igniter, flow sensor, or venting can be replaced individually. A contractor can diagnose which part is causing the problem, whether it's no hot water, water that's too hot or too cold, or an error code on the unit's display.
