What a power outage means for your water heater
Arizona households lost power for 24 hours or more at a rate of 7% in 2024. A gas water heater with a standing pilot stays lit through that and keeps making hot water. A gas unit with electronic ignition or an electric water heater needs power to come back before it works again, and most reset on their own once it does. If yours doesn't relight or come back after the power returns, that's worth having looked at.

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 failed. Water heaters rust from the inside as sediment builds up on the bottom, and once that tank wears through, it leaks and doesn't stop. It can also be the drain valve or a fitting that has loosened, which a contractor can tighten or replace. If the leak is coming from the tank body, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft blowing the flame out can also cause this. A contractor can test the thermocouple and replace it if it's reading weak.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is common and can be flushed out, and parts like the igniter, flow sensor or venting can be replaced. A contractor can diagnose which part is causing the problem and price the repair for your unit.
