Cold groundwater and long winters wear on your water heater in Garrison
Your water heater works harder here than the number on its side suggests. Groundwater coming into the house in December through February is close to freezing, so the unit has to work harder to bring it up to temperature, and it does this for nine months of the year while the house also needs heat. That extra work falls on the heating element or the burner, and on the thermostat that tells it when to fire.
McLean County sees real winter storms, 27 of them over the last ten years, along with 88 damaging wind events. Storms like these knock out power, and North Dakota households went without power for at least 24 hours in 7% of cases last year. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition will not light until power is back, and if the outage hits during a hard freeze, a tank or line that is not draining right can freeze and split.

A new water heater would cut about $50 a year off hot water for a typical North Dakota 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 is cracked from the inside. Sediment builds up at the bottom of the tank over the years, and it traps moisture against the steel until a hole forms. Once the tank is leaking this way it cannot be patched or repaired, it needs to be replaced. A puddle at the base can also come from a loose drain valve or a fitting on the water lines, which a contractor can check before assuming the tank is done for.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out it can't confirm the flame anymore, so the valve shuts the gas off as a safety measure. A weak pilot flame, a draft blowing across it, or a dirty pilot orifice can cause the same thing. A contractor can test the thermocouple and replace it, which usually solves the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral scale on the heat exchanger, or a faulty flow sensor can all be fixed without replacing the unit. Tankless units also run diagnostic codes that tell a technician what failed, which makes finding the problem faster. A full replacement is usually only needed if the heat exchanger itself has cracked or corroded through.
