What outages do to your water heater
Maricopa has logged 45 winter storms and 150 damaging wind events over the past ten years. Weather like that is what knocks the power out. Across Arizona, 7% of households lost power for 24 hours or more in 2024.
Most electric water heaters come back on by themselves once power returns. A gas water heater with electronic ignition often will not relight on its own, and the first sign is water that runs cold with no warning. Homes here need heat from November through March, so a water heater that stays out after an outage is worth checking during those months.

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 from the inside and is leaking, which means the water heater needs to be replaced, not repaired. Water heaters corrode from the inside over years of holding hot water, and once the tank wall is breached there is no patch that holds. A leak from the bottom can also come from a loose drain valve or a fitting, which a contractor can check before condemning the tank. Shut off the water supply to the heater and the power or gas to it until someone can look at it, since a failing tank can fail further without warning.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is almost always a worn thermocouple, the small sensor that tells the gas valve the flame is burning. When it wears out, it fails to signal the valve and the gas shuts off even though the pilot lit fine a moment ago. A draft blowing across the pilot or a dirty pilot orifice can cause the same thing. This is gas equipment, so it's worth having a licensed contractor check it rather than repeatedly relighting it yourself.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, a clogged inlet filter, or an error code from a sensor are all things a contractor can diagnose and fix without replacing the unit. Hard water speeds up mineral buildup inside the exchanger, so a unit that's gone a long time without descaling may need that done before it will fire reliably again. Whether repair or replacement makes more sense depends on the age of the unit and what's actually failed, which a contractor can tell you after looking at it.
