What winter and power outages do to a water heater in Meridian
Meridian doesn't get hard freezes, but winter nights average 37°F from December through February, and colder incoming water means the burner or heating element has to work longer to keep up. A weak thermostat or a failing element tends to show up right when the house wants hot water most.
Power is the other risk. Lauderdale County has logged 126 damaging wind events and 4 winter storms over the past ten years, and across Mississippi, 30% of households went at least 24 hours without power in 2024. A standing pilot keeps a gas water heater running through an outage, but most electric units and any with electronic ignition need the power back on to relight. If the water heater was already struggling, an outage like that is often what finishes it off.

A new water heater would cut about $260 a year off hot water for a typical Mississippi home.

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 itself has likely rusted through and is holding a small crack somewhere along the bottom seam. Water heaters aren't meant to be repaired once the tank leaks, since the steel has corroded from the inside out and any fix would only hold for a short time. It could also be the drain valve or a fitting that's simply loose, which is a much easier fix. Shut off the water supply and power or gas to the unit, then have a contractor look at it before more water gets on the floor.
- Why won't the pilot light on my water heater stay lit?
- A pilot light that won't stay lit is usually a sign the thermocouple has worn out. That's the small sensor that sits in the flame and tells the gas valve it's safe to keep the gas flowing. When it fails, the valve shuts the gas off as a safety measure, even though you just lit the flame. It can also mean a draft is blowing the flame out or the gas valve itself is failing. A contractor can test the thermocouple and replace it, which is a straightforward repair.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the whole unit. Common issues are a clogged inlet filter, mineral buildup on the heat exchanger, or a failed igniter, and all of those can be cleaned or swapped out. The exhaust venting can also fail or get blocked, which a contractor needs to check since it affects how safely the unit runs. If the heat exchanger itself has cracked, that's a bigger repair and sometimes replacement makes more sense.
