Winter is hard on a water heater in Dunn
Water heaters in Harnett County work harder from October through March, when incoming water runs cold and the heater has to make up more ground to hit the temperature you set. That extra work falls on the heating element or the burner, and on the thermostat that tells it when to fire.
Power is part of the problem too. A quarter of North Carolina households went at least a day without power in 2024, and this area has seen 76 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with an electric ignition won't come back on until the power does, and some need the pilot relit by hand.

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. It could also be a loose drain valve, a failed temperature and pressure relief valve, or condensation if you just installed a new gas unit. A contractor can check the fittings and valves first, but if the tank is the source, it will need to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple has likely worn out and stopped sensing that the pilot is lit, so it shuts the gas off as a safety measure. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and clean or replace it, which usually solves the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter, all of which a contractor can clean or replace without swapping the whole unit. Error codes on the display usually point straight to which part needs attention.
