Dallas County water heaters answer to the power grid
Dallas County has had 22 winter storms and 145 damaging wind events over the past ten years. Any one of them can knock out power to your block for hours, sometimes longer. Statewide last year, a third of households went at least a full day without it.
A gas water heater with a standing pilot will keep working through an outage. One with an electronic ignition will not light again until the power is back and someone resets it. Electric water heaters just stop, and most come back on their own once the power returns. If yours never fired back up, or the water never got hot again, that is worth a look.

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?
- The tank itself has likely rusted through and is holding water it can no longer contain. Water heaters corrode from the inside as the glass lining wears down over the years, and once the steel underneath is exposed, it rusts and eventually pits or cracks. A loose drain valve or a fitting at the bottom can also leak and look like the same problem, so it is worth checking those before assuming the tank is bad. If the tank itself is the source, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple has worn out and is no longer telling the gas valve the pilot is lit, so the valve shuts the gas off. A weak or dirty pilot flame can cause the same thing, and a draft near the burner compartment can blow the flame out before it ever gets the chance. A cracked thermocouple or a bad gas valve are both things a licensed contractor can test for and replace. If your water heater has a standing pilot, it will not go out just because the power went out, since that flame does not run on electricity.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be fixed without replacing the unit. Mineral buildup on the heat exchanger is a common issue and usually calls for a descaling flush rather than new parts. Igniters, flow sensors, and venting issues can also be repaired on their own. A contractor licensed by the Texas Department of Licensing and Regulation can flush and diagnose the unit to tell you what it actually needs.
