What Lancaster County does to a water heater
Winter nights here average 33°F from December through February, cold enough that incoming water is much colder than the rest of the year. Your water heater has to work harder to bring it up to temperature, and that extra load falls on the heating element or the gas burner assembly first.
Power is the other issue. Nearly half of South Carolina households went at least 24 hours without power in 2024, and this county has logged 133 damaging wind events and 5 winter storms over the past ten years. An electric water heater goes cold the moment power drops. Most units come back on by themselves once power returns, but if yours is out after a storm and stays cold, that is worth checking before you assume something broke.

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 and is failing from the inside. Water heaters have a steel tank with a glass lining, and once that lining cracks, rust eats through the metal and water finds a way out the bottom. Sometimes what looks like a tank leak is actually the drain valve or a loose fitting, which a contractor can check in a few minutes. If the tank itself is rusted through, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and clean or replace the parts that are causing it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues include a buildup of mineral scale on the heat exchanger, a failed igniter, or an error code pointing to a sensor or flow problem. A contractor can diagnose which part is causing the issue and replace it without needing to replace the whole unit. Regular flushing to clear mineral buildup also helps prevent some of these failures.
