What power outages do to a water heater
Harrison County has logged 53 damaging wind events over the past ten years, and in 2024 nearly a third of Mississippi households lost power for 24 hours or more. Every time the power drops and comes back, an electric water heater's heating element and thermostat take a jolt, and a gas unit's pilot light can go out and stay out.
Most homeowners notice it as water that used to run hot turning lukewarm, or no hot water at all until someone relights the pilot. With most homes in the county owner-occupied, that is a repair that falls to you, not a landlord.

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 from the inside and is starting to fail. Water heaters have an inner tank that holds and heats water for years, and once that liner corrodes, water finds a way out through the bottom. It can also be a loose drain valve or a failed temperature and pressure relief valve, both of which a contractor can check in minutes. If the leak is coming from the tank itself, the unit needs to be replaced, not patched.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit usually means the thermocouple has worn out. That's the small sensor that sits in the flame and tells the gas valve it's safe to keep gas flowing. When it wears out or gets coated with soot, it stops sensing the flame correctly and shuts the gas off, even though the pilot lit fine. A dirty pilot orifice or a draft blowing out the flame can cause the same problem, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairs, not replacements. Common issues are a scaled-up heat exchanger, a failed flow sensor, or an igniter that won't fire, and all of those can be serviced without replacing the unit. Tankless heaters run for many years when the heat exchanger is kept clear of mineral buildup, so a repair now often means a long stretch before anything else goes wrong. A contractor can tell you which part is failing once they've looked at the error code on the unit.
