Power comes and goes here, and your water heater feels it
Livingston Parish sees storms often enough that losing power is normal, not rare. Louisiana households went at least 24 hours without power in 2024 nearly half the time, and the parish has logged 59 damaging wind events over the past ten years. Every time the power drops and comes back, your water heater's gas valve or electric elements have to reset and pick up where they left off.
Most tank water heaters recover on their own once power is restored, but a unit that's already struggling can fail to relight or trip a limit switch instead. With most homes here owned by the people living in them, that usually means no hot water until someone catches it, sometimes not until the next shower runs cold.

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 reason is that the tank itself has rusted through from the inside and is failing. Water heaters corrode over years of holding hot water, and once the tank wall gives way, the leak will not stop or seal itself. It can also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If the tank is the source, replacement is the only real fix, since a rusted tank cannot be patched or repaired.
- Why won't the pilot light on my water heater stay lit?
- This usually points to the 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, so the pilot won't hold. A dirty pilot orifice or a draft in the area can cause the same problem. A contractor can test the thermocouple directly and replace it if it is not holding a reading.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like error codes, ignition failure, or reduced hot water flow are often traced to a specific part, such as the igniter, a sensor, or mineral buildup on the heat exchanger. A contractor can diagnose which part is causing the problem and repair or replace it rather than the whole unit. Whether repair makes sense for a specific unit depends on its age and what the diagnosis finds.
