What Pascagoula's weather does to your water heater
Your water heater works harder here than the mild winters might suggest. Nights average 42°F from December through February, cold enough that the tank cycles on more to keep water hot, and that extra cycling adds wear to the heating element or burner over the season.
Jackson County also sees its share of storms, 29 damaging wind events over the past ten years, and Mississippi households lost power for 24 hours or more at a high rate in 2024. When the power drops and comes back, an electric water heater usually resets on its own, but a gas unit with an electronic ignition may need someone to relight it. If your water heater will not fire back up after an outage, or you are noticing less hot water than usual, that is often where to start looking.

A new water heater would cut about $260 a year off hot water for a typical Mississippi 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 most common reason is that the tank itself has rusted through and is failing from the inside. Sediment builds up at the bottom of the tank over years, and once it corrodes a hole in the steel, water works its way out and no seal or fitting will stop it. A leak can also come from the drain valve or a fitting on top that drips down the side and pools at the bottom, so it looks like a tank leak but isn't. A contractor can tell the difference quickly by drying the area and watching where the water shows up first. If it's the tank, the water heater needs to be replaced rather than repaired.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer sense that the pilot is burning. The thermocouple is a safety part that shuts off the gas if it doesn't detect flame, and once it weakens, it cuts the gas even when the pilot is lit fine. A dirty pilot orifice or a draft can also blow the flame out, so it's worth checking that the area around the pilot is clean and free of debris. If relighting it doesn't hold, the thermocouple is the part to have checked first.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable rather than a reason to replace the unit. Common issues include a clogged inlet filter, mineral buildup on the heat exchanger, a failed igniter, or an error code pointing to a sensor problem. Mineral scale is a bigger factor in tankless units than tank units because the heat exchanger has narrow passages that scale can narrow over time. A contractor can flush the unit or replace the specific failed part rather than the whole system in most cases.
