Corpus Christi doesn't ask much of your water heater, until the power goes out
Most of the year your water heater in Corpus Christi has an easy job. Winters are short, nights average 50°F even in the coldest months, and the tank isn't working hard to make up ground. That's not where the trouble starts.
The trouble is the grid. Nueces County has logged 8 winter storms and 85 damaging wind events over the past ten years, and across Texas a third of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage like that. One with electric ignition won't relight until the power is back, and if it doesn't come back on its own, you're stuck with cold water until someone resets it. Storms like these are also hard on the thermostat and the ignition control itself, the parts that fail quietly and only show themselves the next time you need hot water.

A new water heater would cut about $290 a year off hot water for a typical Texas 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, not something that can be patched. Water heaters corrode from the inside over the years, and once the tank wall gives way, the only fix is replacing the unit. A puddle can also come from a loose drain valve or a fitting at the bottom, which a contractor can tighten or replace without touching the tank. If the leak is coming from underneath the tank itself rather than a connection, that unit is done and shutting off the water and power to it is the right move until someone can look at it.
- 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 it stops sensing the flame correctly and shuts the gas off even though the pilot is lit. A dirty or clogged pilot tube can cause the same problem by starving the flame. Either one is a straightforward repair for a licensed contractor, and it is not something to keep relighting on your own if it keeps going out.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush, especially important if the unit hasn't been serviced in a while. Igniters, flow sensors, and venting issues can all be replaced or corrected without swapping the whole unit. A contractor licensed by the Texas Department of Licensing and Regulation can diagnose which part is failing and price the repair for your specific unit.
