Lafourche Parish is hard on a water heater in its own way
Your water heater does not fight the cold here the way one does further north. Winter is short, four months of it, and nights average 47°F. But Lafourche Parish loses power. Statewide, about half of households went at least a day without electricity in 2024, and the parish has logged 16 damaging wind events over the past ten years.
When the power drops, an electric water heater stops heating until it comes back on, and it will come back on by itself when it does. A gas water heater with a standing pilot keeps working through the outage, since the pilot needs no power at all. What fails after a storm is usually the wiring or the thermostat that got wet or jarred, not the tank itself. If your water heater will not fire back up once the lights are on, that is what a repair call is checking first.

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?
- The most common cause is the tank itself has rusted through from the inside and is failing. Sediment builds up at the bottom of the tank over the years and traps moisture against the steel until it corrodes. Water pooling under the tank can also come from a leaking drain valve or a fitting that has worked loose, and those can be fixed. A tank leaking from a crack in the steel cannot be repaired and the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and needs to be replaced. The thermocouple is the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep gas flowing. Once it wears out, it fails to sense the flame properly and shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft blowing on the flame can cause the same problem, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a buildup of mineral scale on the heat exchanger, a failed igniter, or an error code pointing to a specific sensor or part. A contractor can flush the unit to clear scale or replace the failed part in most cases. How much of the unit can be saved depends on its condition, which a contractor will need to look at in person.
