Cold groundwater and long winters work your water heater hard in Sidney
Groundwater coming into your house is cold most of the year, and from September through May the burner or heating element has to work harder to bring it up to temperature. That is nine months of heavy cycling on the thermostat, the thermocouple or igniter, and the heating element itself.
Winter nights here average 6°F, and cold like that makes any weak part fail sooner. Richland County has logged 18 winter storms and 91 damaging wind events over the past ten years, and storms like these knock out power. Montana households saw outages of 24 hours or longer 18% of the time in 2024. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition will not light again until power comes back, and if the power cut out while it was heating, you may need to relight it or reset it yourself.

A new water heater would cut about $60 a year off hot water for a typical Montana home.

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 the tank needs to be replaced, not patched. Sediment builds up at the bottom of the tank over the years, and it slowly wears through the steel from the inside. Water can also drip from the bottom if a valve or fitting above the tank is loose, so check those before assuming the worst. If the leak is coming from the tank itself, shut off the water supply to the heater and call a contractor before it gets worse.
- Why won't the pilot light on my water heater stay lit?
- This usually points to the thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, the valve shuts off the gas as a safety measure, and the pilot goes out. A dirty pilot tube or a draft in the room can cause the same thing. A contractor can test the thermocouple and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. The igniter, the flow sensor, and the heat exchanger are the parts that tend to fail, and each can usually be replaced on its own. Mineral buildup inside the unit is common too, and flushing it often restores hot water flow. A contractor will need to look at the unit to say whether a part needs replacing or a flush will do.
