Cold nights and outages both take a toll on Safford water heaters
From December through February, nights here average 33°F. Water coming into your house is colder too, so the burner or heating element has to run longer to bring a tank of water up to temperature. That extra runtime is what wears out a thermocouple or a heating element ahead of schedule.
Power does not always stay on to run it. Graham County has logged 50 winter storms and 61 damaging wind events over the past ten years, and statewide, 7% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot keeps working through an outage like that. One with an electronic igniter will not relight on its own, and an electric water heater just stops until power comes back. If your water heater has gone cold and stayed cold, that is often why.

A new water heater would cut about $80 a year off hot water for a typical Arizona 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 starting to fail. Sediment builds up in the bottom of the tank over the years, and it eats away at the lining from the inside until a leak forms. It can also be a loose drain valve or a fitting that has failed, which a contractor can check before assuming the worst. Once the tank itself is leaking, though, 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 thermocouple that has worn out and no longer signals the gas valve to stay open. A weak or dirty thermocouple will let the pilot light but then shut the gas off within seconds, since it senses the flame is not being held steady enough. Dirt or a spider's nest in the pilot tube can also block the flame path. A contractor can test the thermocouple and clean the assembly to find out which one it is.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. The heat exchanger, igniter, and flow sensor are the parts that fail most often, and they can be replaced individually. Mineral buildup inside the unit is common too, and flushing the system often restores hot water flow and heating. A contractor licensed by the Arizona Registrar of Contractors can diagnose which part is causing the trouble.
