Grafton winters push your water heater hard
Groundwater coming into your house is already cold, and in a Walsh County winter it comes in colder still, with nights averaging 1°F from December through February. Your water heater has to work harder to make up that difference, and it does that work nine months of the year, September through May. That kind of steady demand wears on the heating element or the burner assembly, and on the thermostat that tells it when to fire.
The area has seen 102 winter storms and 71 damaging wind events over the past ten years, and statewide, 7% of households lost power for at least 24 hours in 2024. An electric water heater will not heat while the power is out. A gas one with a standing pilot will keep working, but if the power drops during a storm and comes back, it is worth checking that yours actually recovered and is heating again.

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 has rusted through from the inside and is leaking, and that means replacement, not repair. The tank has a lining, but once that lining fails the steel underneath corrodes until it gives way. A leak can also come from a loose drain valve or a fitting near the bottom, and those can sometimes be fixed instead of replaced. A contractor can tell you which one you have and price the job from there.
- Why won't the pilot light on my water heater stay lit?
- The usual cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. Once it wears out, it can't confirm the flame is lit, so the gas valve shuts off even though the pilot is burning. A dirty pilot orifice or a draft near the burner can also blow the flame out. A contractor can test the thermocouple and replace it if that's the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common causes include mineral scale built up on the heat exchanger, a failed igniter, or an error code pointing to a bad sensor. A contractor can run the diagnostics for the specific error code and tell you what needs to be fixed.
