Nine months of cold water wears on your water heater
Wisconsin Rapids homes need heat from September through May, and that same cold is working on your water heater the whole time. Groundwater coming in that cold means longer burner or element run times to get it up to temperature, and that extra run time adds wear to the thermostat, the heating element, or the gas valve.
Power is the other piece. Wood County has seen 25 winter storms and 47 damaging wind events over the past ten years, and in 2024, 18% of Wisconsin households lost power for 24 hours or more. A standing pilot will keep a gas water heater running through an outage. Most units with electric ignition or an electric thermostat will not, and need to be checked once power is back.

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 of the time it means the tank itself has rusted through and is failing. Water heaters corrode from the inside out over years of use, and once the tank starts leaking there is no patching it. Sometimes what looks like a tank leak is actually the drain valve or a loose fitting, which a contractor can check in a few minutes. If it is the tank, the water heater needs to be replaced, not repaired.
- 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 sense the flame anymore, so the gas valve shuts off the pilot as a safety measure. A weak pilot flame, a draft blowing on it, or a dirty pilot orifice can cause the same problem. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the whole unit. Common issues are a clogged inlet filter, mineral scale built up in the heat exchanger, or a failed igniter, and each of those can be serviced on its own. A contractor can diagnose which part is causing the problem and price the repair for your unit.
