Long winters and power outages both take a toll here
Water heaters in Whitewater run harder from October through May, when incoming water is coldest and homes ask the most of them. That extra run time is what wears down a heating element, a thermostat, or an igniter before its time.
Walworth County also gets winter storms and damaging wind, and both can knock out power. Statewide, 18% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot keeps working through that. One with electronic ignition, or any electric water heater, will not come back on until the power does.

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 from the inside and is cracked. Once that happens the tank cannot be sealed or patched, because the rust starts inside where you cannot reach it. Sometimes the leak is coming from a fitting, the drain valve, or the temperature and pressure relief valve instead, and those can be replaced without replacing the tank. A contractor needs to look at where the water is actually coming from before you know which one you are dealing with.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the pilot is lit, so the gas valve shuts it off. A dirty pilot orifice or a draft pulling the flame around can do the same thing. Both are common repairs and do not mean the water heater needs to be replaced. If the pilot won't even light at all, the gas valve itself may be the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairs, not replacements. The heat exchanger, the igniter, the flow sensor, and the venting can all be serviced or replaced on their own. Mineral buildup inside the unit is a common issue in areas with hard water and is cleared with a descaling flush rather than a new unit. A contractor can tell you which part is failing once they've checked the error code the unit is showing.
