Step 1 of 3: Equipment
Cold winters and outages both take a toll here
From December through February, nights in Jackson average 32°F. Your water heater works harder through those months, and a heating element or gas valve that is already worn is more likely to fail when it is running that much. You will notice hot water running out fast, or water that never gets past lukewarm.
Power outages add to this. In 2024, 20% of Tennessee households went at least 24 hours without power. Most water heaters come back on by themselves once power returns, but if yours does not, cold water is the first sign something needs a look.

- Why is my water heater leaking from the bottom?
- The most common reason is that the tank itself has rusted through and is failing from the inside. Sediment builds up at the bottom of the tank over the years, and once it corrodes a hole in the steel, water will find its way out. A leak can also come from the drain valve or a fitting that has loosened, which a contractor can check before assuming the tank is done. If the tank is the source, it needs to be replaced rather than repaired, since there is no way to patch a hole in a pressurized tank.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the pilot is burning, so the gas valve shuts it off. A weak or dirty pilot flame can cause the same problem, and so can a draft reaching the pilot from a vent or nearby door. Winters here run cold enough, with nights averaging 32°F from December through February, that a water heater that keeps failing is worth getting looked at before the weather gets worse. A contractor can test the thermocouple and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the whole unit. Common repairs include descaling the heat exchanger, replacing an igniter or flow sensor, or clearing a blocked vent. Because tankless units run on electronic controls, a contractor needs to diagnose the specific error before knowing which part is at fault.
