Jackson County winters push water heaters hard
Groundwater coming into your house is cold from October through April, and on nights near 23°F your water heater works harder to make up the difference. The burner or heating element runs longer and cycles more to keep up, and that extra work wears on the thermostat and the heating element or gas valve sooner than it would in a mild month.
Power loss is part of the picture too. Missouri saw 19% of households lose power for a full day or more in 2024, and Jackson County has logged 10 winter storms and 212 damaging wind events over the past ten years. A gas water heater with an electronic ignition will not relight itself after an outage, so you may find yourself with cold water and a pilot that will not stay lit until it is reset.

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 tank has likely rusted through from the inside and is leaking water it can no longer hold. A water heater tank corrodes over years as the glass lining wears down and exposes the steel underneath. Once the tank itself is leaking, it needs to be replaced, not repaired. Water pooling at the base can also come from a loose drain valve or a fitting on the cold and hot lines, so it is worth checking those before assuming the tank is the problem.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple is failing and no longer telling the gas valve the flame is lit. The thermocouple sits in the pilot flame and sends a small signal that keeps the gas valve open. When it wears out or sits out of position, the valve reads no flame and shuts the gas off, even while the pilot is burning. A dirty pilot orifice or a draft blowing the flame around can cause the same thing, so a contractor will check both before replacing parts.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be fixed without replacing the unit. Common repairs include cleaning mineral buildup from the heat exchanger, replacing an igniter, or clearing a blocked vent. Because a tankless unit runs on demand rather than holding water, hard water scale is one of the more frequent issues, especially where minerals build up faster than in a tank system. A contractor can pull the error code the unit is showing and tell you what is actually wrong with it.
