What Greenville's power outages do to your water heater
Pitt County sees its share of wind. Ten years of records show 67 damaging wind events and 6 winter storms, and across North Carolina a quarter of households lost power for at least 24 hours in 2024. A water heater rides that out fine most of the time. Gas units with a standing pilot keep working straight through, and electric units just pick back up once the power returns.
What catches people out is the reset. Some electric water heaters have a high limit switch that trips during a power surge and needs a manual reset before the unit will heat again. If your water is cold after the lights come back on, that switch is often why.

A new water heater would cut about $300 a year off hot water for a typical North Carolina 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 and is leaking from the inside out. Water heater tanks have a glass lining that protects the steel, and once that lining cracks, the tank corrodes and starts to weep at a seam or fitting near the bottom. A leak could also come from the drain valve or a fitting that has loosened, which a contractor can tighten or replace. But if the tank itself is leaking, the tank needs to be replaced, since a corroded tank cannot be patched or sealed.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep sending gas. When it wears out, it stops sensing the flame correctly and shuts the gas off, even though the pilot lit fine a moment ago. 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, which usually solves the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a blocked vent, mineral buildup on the heat exchanger, or a faulty flow sensor can all be fixed without replacing the unit. Tankless units also run diagnostic codes that point a contractor straight to the failed part. Replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
