Cold groundwater and long winters wear on your water heater here
Winter nights in Rigby average 11°F, December through February, and the water coming into your tank starts out that cold. The heating element or burner has to work harder and longer to bring it up to temperature, and that extra strain adds up over a winter that stretches from September through June. Ten months of near-constant demand takes its toll on the parts that do the heating.
Jefferson County has seen 58 winter storms and 144 damaging wind events over the past ten years, and power failures follow. If your water heater is electric, an outage stops it cold, and you will notice when the water runs lukewarm or cold until power is back. Gas water heaters with a standing pilot keep working through an outage, but if yours has electronic ignition, it will need power to relight.

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?
- The most common cause is the tank itself rusting through from the inside, and once that happens the tank needs to be replaced, not patched. Water pooling underneath can also come from a loose drain valve, a failed temperature and pressure relief valve, or fittings that have loosened over time, and those can often be fixed without replacing the tank. A leak from a cracked tank tends to be slow at first and gets worse, so it is worth having someone look at it before it lets go all at once.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer signaling the gas valve to stay open. A weak or dirty thermocouple reads the pilot flame incorrectly and shuts the gas off even though the flame is still lit. It can also mean a draft is blowing the pilot out, or the gas valve itself is failing. A standing pilot does not use any electricity, so a power outage is not the cause here.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a buildup of mineral scale on the heat exchanger, a failed igniter, or an error code pointing to a sensor problem, and a contractor can usually fix these without replacing the unit. If the heat exchanger itself has cracked or corroded, that is a bigger repair and sometimes replacement makes more sense. A contractor can look at the specific error and give you an honest read on which one you are dealing with.
