Galveston County power gets shaky, and your water heater feels it
League City doesn't ask much of a water heater in winter. Nights average 48°F from December through February, so the tank isn't working hard to make up for cold groundwater the way homes further north do. What it does have to deal with is the power going out. Texas saw a third of households lose power for 24 hours or more in 2024, and Galveston County has logged 48 damaging wind events over the past ten years. Most electric water heaters come back on by themselves once power returns, and a standing pilot on a gas unit never needed power in the first place. But a storm that knocks out power for days can leave sediment settling harder in the tank, and if the unit was already due for a flush, that's when a homeowner notices lukewarm water or a tank that takes longer to recover.

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 often the tank itself has rusted through from the inside and is starting to fail. Sediment builds up at the bottom of the tank over years and eats away at the lining, and once the steel underneath is exposed it will corrode and leak. A leak can also come from a loose drain valve or a fitting that has worked itself loose, and those are worth checking first since they can be fixed instead of replaced. If the tank is the source, the water heater needs to be replaced, not repaired.
- 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 can't sense the flame anymore, so the valve shuts off the gas as a safety measure. A dirty pilot orifice or a draft blowing the flame out can cause the same problem. A standing pilot doesn't use any electricity, so this isn't something a power outage would cause.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral scale on the heat exchanger, or an error code from a bad sensor can all be fixed without replacing the unit. A contractor can run the diagnostics for the specific model and tell you whether it's a repair or if the unit has failed beyond that point.
