Ten months of cold water in Rolette County
Your water heater works nearly year round here. From September through June the ground and the water coming into the tank stay cold, and with winter nights averaging 0°F, that water is about as cold as it gets. The burner or heating element has to run longer each time just to bring a tank up to temperature.
That extra runtime wears on the parts that do the heating. A gas unit's burner and igniter cycle more often. An electric unit's heating element stays on longer per cycle. You may notice the water taking longer to heat back up between showers, or the tank running out of hot water sooner than it used to. Power matters too. Rolette County has seen 33 winter storms in the past ten years, and statewide, 7% of households went at least a day without power in 2024. A water heater that loses power stops heating until it comes back on.

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 is starting to fail. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the metal underneath corrodes until it gives way. Sediment that builds up at the bottom of the tank over the years speeds this up. A leak from the bottom usually means the tank needs to be replaced, not patched, since a cracked tank cannot be sealed. If the leak is actually coming from a fitting, valve, or the drain at the bottom, a contractor can check that separately, since those can sometimes be repaired instead.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a thermocouple or flame sensor that has worn out and can no longer tell the gas valve the pilot is burning. When that happens, the valve shuts off the gas as a safety measure, even though the flame is still lit or was lit moments before. A dirty or misaligned pilot orifice can cause the same problem. A weak gas supply or a draft blowing out the flame can also be the cause, so it is worth checking if the pilot goes out right after lighting it or only after it has run a while. A contractor can test the thermocouple and the gas valve to find out which part is failing.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a failed igniter, a clogged inlet filter, mineral scale built up on the heat exchanger, or an error code pointing to a sensor problem. Hard water speeds up scale buildup inside the heat exchanger, which is one of the most frequent reasons these units stop heating properly or shut down. A contractor can read the error code the unit is showing and flush or replace the part causing it.
