What Sedalia winters do to a water heater
Groundwater coming into your house runs cold from October through April, seven months of the year, and the water heater has to work harder to bring it up to temperature than it does in summer. That extra work falls on the heating element or the burner, and on the thermostat that tells it when to fire. When one of those wears out, you notice hot water that runs out fast or never gets hot at all.
Pettis County has seen 8 winter storms and 47 damaging wind events over the past ten years, and in 2024 nineteen percent of Missouri households lost power for at least 24 hours. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition will not light again until the power is back.

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 cause is the tank itself corroding from the inside and starting to fail. Sediment builds up at the bottom of the tank over years, and it traps moisture against the steel until it wears through. A leak from the bottom can also come from a loose drain valve or fittings, which a contractor can check before condemning the tank. If the tank itself is leaking, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep gas flowing. When it fails, the valve shuts the gas off as soon as you let go of it, even though the flame lit fine. A dirty pilot orifice or a draft blowing the flame around can cause the same symptom, so a contractor needs to look at it to know which one it is.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter, and all of those can be serviced without replacing the unit. Error codes on the display usually point straight to which part is causing the trouble. A contractor can read the code and tell you whether it's a repair or something more serious.
