What outages in Lafayette Parish do to a water heater
Winter nights here average 44°F from December through February, mild enough that the tank itself is not what's at risk. The power behind it is the weaker point. Nearly half of Louisiana households went at least 24 hours without power in 2024, and the parish has logged 39 damaging wind events and 2 winter storms over the past ten years.
Most gas water heaters come back on by themselves once power returns, and a standing pilot never needed power to begin with. But if yours uses electric ignition, it may need to be relit or reset by hand. If your water isn't heating after an outage and the pilot is out, that is often the whole problem.

A new water heater would cut about $250 a year off hot water for a typical Louisiana 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?
- Most of the time this means the tank itself has rusted through and is failing, and it needs to be replaced rather than repaired. Sediment builds up at the bottom of the tank over years and corrodes the steel from the inside, so by the time you see water on the floor the tank is already breached. It can also be a loose drain valve or a fitting weeping from above and running down the side, which a contractor can check before assuming the worst. Either way, shut off the power or gas to the unit and the cold water supply line until someone looks at it, since a cracked tank will keep leaking and won't seal itself.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to stay open. Once it wears out it can't hold that signal, so the valve shuts the gas off and the pilot goes out, even though the flame looked fine. It can also be a weak gas valve or a draft blowing the pilot out, so a contractor should test which one it is rather than replacing parts by guess. A standing pilot doesn't run on electricity, so a power outage isn't the cause here.
- Can a tankless water heater be repaired?
- Yes, most tankless problems come down to a handful of parts, like the igniter, the flow sensor, or a heat exchanger clogged with scale, and a contractor can usually replace or clean these without replacing the whole unit. Error codes on the display help narrow down which part is failing before a repair starts. Mineral buildup is the biggest reason repairs are needed at all, so a unit that's never been descaled is more likely to need a part replaced. A contractor can look at the unit and the error history and tell you whether repair or replacement makes more sense for that specific machine.
