Cold water and outages take a toll on your water heater
Winter nights in Oxford average 34°F from December through February, and your water heater works harder those months to bring cold water up to temperature. That extra work falls on the heating element or burner, and on the thermostat that tells it when to fire.
Mississippi households saw real power interruptions last year, with 30% losing power for 24 hours or more. An electric water heater does nothing until power comes back, and some units need the reset button pressed before they will heat again. Lafayette County has also logged 8 winter storms and 46 damaging wind events over the past ten years, the kind of weather that knocks power out in the first place. If your water is running cold and nothing seems to have failed inside the tank, the outage itself may be the reason.

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 that means it needs to be replaced, not repaired. Water heater tanks corrode from the inside over years, and once the tank wall is breached, no sealant or patch holds. What looks like a bottom leak can also come from a loose drain valve or a fitting above the tank, with water running down the side and pooling underneath. A contractor can tell you which one it is by drying the tank off and watching where the water shows up first.
- 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 pilot flame and tells the gas valve it is safe to keep the gas flowing. When it fails, the valve shuts the gas off as a safety measure, even though the flame was there a second ago. It can also mean a draft is blowing the flame out or the pilot orifice is partly clogged, but a worn thermocouple is the most common cause and it's a straightforward part to replace.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems can be repaired without replacing the whole unit. Common issues are a clogged inlet filter, mineral scale built up on the heat exchanger, or an ignition or flow sensor that has failed. Tankless units also run diagnostic codes on a display or through a series of blinks, which point a contractor straight to the problem. Regular flushing of the heat exchanger helps it keep running the way it should.
