What Oklahoma City winters do to your water heater
Your water heater works harder from October through April, seven months of the year, when incoming water runs colder and the tank has to make up more ground to keep the temperature you set. On nights that average 30°F, that gap is bigger, and the burner or heating element cycles more to close it.
Oklahoma City also sees storms that cut power. Statewide, a quarter of households went at least a day without electricity in 2024, and the county has logged 15 winter storms and 253 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep running through an outage. One with electric ignition will not light again until power is back. After a storm knocks the power out, that is often when a homeowner finds out which kind they have.

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 corroded through and is failing. Sediment builds up on the bottom of the tank over years, and it eats away at the steel underneath until a crack or hole forms. Once a tank is leaking this way, it needs to be replaced, not patched. A leak at the bottom can also come from a loose drain valve or a fitting that has failed, and those can sometimes be repaired, so it is worth having a contractor look before assuming the tank is done.
- Why won't the pilot light on my water heater stay lit?
- This usually means the thermocouple has worn out and is no longer telling the gas valve that the pilot is lit. The thermocouple is a safety part, and when it fails, the valve shuts off gas to the pilot even though the flame is 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 that is the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues include a clogged inlet filter, mineral buildup on the heat exchanger, a failed igniter, or an error code pointing to a specific sensor. A contractor can read the unit's diagnostic code to find the part causing the problem and repair or replace just that part rather than the whole unit.
