In Webb County, power is what usually takes down a water heater
Your water heater here does not fight much cold. Winters are short, just December through February, with nights averaging 47°F, so the tank is not working against the weather the way heating equipment would somewhere colder.
What it does face is the power going out. A third of Texas households were without power for 24 hours or more in 2024, and Webb County has logged 31 damaging wind events over the past ten years. Most electric water heaters come back on by themselves once power returns, but a storm that trips a breaker or knocks out a line can leave you with cold water until someone checks it.

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 often the tank itself has rusted through from the inside and is starting to fail. Water heaters have a steel tank with a glass lining, and once that lining cracks, the metal underneath corrodes until it gives way. Water pooling under the tank almost always means replacement, not repair, since there's no way to patch a leak inside the tank. It can also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the worst.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is the usual cause. It's the small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. When it wears out or sits out of position, the valve shuts off the gas as a safety measure even though the pilot was burning fine. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and replace it if it's reading weak.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a fouled flow sensor, a failed igniter, mineral buildup on the heat exchanger, or an error code pointing to a bad sensor. Tankless units run water through a heat exchanger on demand rather than storing it, so scale buildup from hard water is one of the most common reasons they start acting up. A contractor can pull the fault code and flush or replace the part that's failing.
