What Dakota County winters do to your water heater
Water coming into your house is colder for eight months of the year here, October through May. Your water heater has to run longer to make up that difference, and the burner or heating element takes the extra wear. That is when a weak heating element or an aging burner finally gives out.
Winter storms add another risk. Dakota County has seen 26 winter storms and 22 damaging wind events over the past ten years, and a quarter of Nebraska households lost power for 24 hours or more in 2024. A gas water heater with an electronic igniter will not relight on its own once power drops. An electric unit just stops heating. Either way you notice it the same way, with water that runs cold and stays that way.

- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself failing from the inside, where sediment builds up over years and corrodes the steel until it lets go at a seam or the bottom. A leaking drain valve or a loose fitting can also drip and look like a tank leak, and those can be fixed. Once the tank itself is rusted through, there is no repair for it, only replacement. A contractor can tell you within a few minutes which one you are dealing with.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer hold the gas valve open once you let go of it. A draft blowing across the pilot, or a dirty pilot tube, can cause the same problem. A standing pilot does not need power to run, so a power outage is not the cause here. A contractor can test the thermocouple in a few minutes and replace it if that is the issue.
- Can a tankless water heater be repaired?
- Yes, most problems in a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues that a contractor can clean or replace without swapping the whole unit. Hard water speeds up the mineral buildup, so descaling on a regular schedule keeps these units running longer. If the heat exchanger itself has cracked, that is the one failure that usually means replacement.
