Sevierville winters put steady strain on your water heater
Your water heater works harder from October through April, 7 months a year, when incoming water runs cold and stays cold. On nights that average 30°F, it cycles more just to hold its set temperature, and every cycle puts a little more wear on the heating element or the burner assembly.
Sevier County has seen 68 winter storms and 157 damaging wind events over the past ten years, and power interruptions come with that kind of weather. A gas water heater with a standing pilot will keep working through an outage, but one with electronic ignition needs the power back before it fires again. If your water runs cold after a storm, that is often why.

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 of the time this means the tank itself has failed. Sediment builds up inside over the years, and it wears through the steel from the inside until a crack or pinhole opens at the bottom. It can also be a loose drain valve or a fitting that has corroded, which a contractor can check before assuming the tank is done. Once the tank itself is leaking, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- This usually points to the thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, the valve shuts off the gas even though the flame is lit. A dirty pilot tube or a draft in the area can also blow the flame out. A weak gas supply is possible too, though that shows up less often than the other two.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues and none of them require replacing the unit. A contractor can flush the system or replace the part that has failed. Tankless units tend to last longer than tank models, so repair is usually the first step, not replacement.
