Sheboygan County winters are hard on a water heater
Groundwater coming into your house is cold nine months of the year, from September through May. That means your water heater is working harder, longer, to bring it up to temperature, and the burner or heating element cycles more to keep up. Sediment settles faster at the bottom of the tank when it's running that much, and that layer insulates the burner from the water above it, so you hear popping or rumbling before you notice anything else.
Wisconsin also loses power in a lot of homes. Statewide, 18% of households went at least 24 hours without it in 2024. A gas water heater with a standing pilot will keep making hot water through an outage, but most electric units and any gas unit with electronic ignition will not come back on their own until power is restored and someone relights or resets it.

A new water heater would cut about $40 a year off hot water for a typical Wisconsin 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?
- The most common reason is the tank itself has rusted through from the inside and is failing. Sediment builds up over years and corrodes the steel, and once the tank is breached there is no patch that fixes it, the unit needs to be replaced. Leaks from the bottom can also come from a loose drain valve or a failed temperature and pressure relief valve dripping down the side, and those can sometimes be repaired instead of replacing the tank. A contractor can tell within a few minutes which one you are dealing with.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing, and once it weakens it shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft blowing the flame around can also cause it. The thermocouple is a low-cost part to replace, so have a contractor check that first before assuming the gas valve itself is bad.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is the most common issue, especially if the unit has never been flushed, and that's a service job rather than a replacement. Ignition failures, sensor errors, and venting blockages are also things a contractor can diagnose and fix. Replacement usually only comes up when the heat exchanger itself has cracked or corroded through.
