Bath winters put water heaters to work
Your water heater runs hardest from September through May, nine months of the year. On nights that average 16°F, incoming water is colder, so the burner or the elements stay on longer to bring a tank up to temperature. That extra runtime wears on a gas control valve or a heating element well before the unit is old.
Most homes in Sagadahoc County own the place they live, so a failing water heater is not a landlord's problem to solve, it is yours. And when a storm knocks out power, the kind that has hit Maine hard enough that over half of households lost power for a full day at some point in 2024, an electric water heater stops heating until power is back, and a tank that was already struggling can take longer to recover.

- Why is my water heater leaking from the bottom?
- Most of the time this means the tank itself has rusted through and is failing. Sediment builds up on the bottom of the tank over years, and it wears through the steel from the inside out. Once the tank is leaking, it cannot be patched or repaired, it needs to be replaced. Water at the bottom can also come from a loose drain valve or a fitting above it dripping down, so a contractor should check that before condemning the tank.
- 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 stops sensing heat correctly and the gas valve shuts off the flame as a safety measure. A dirty pilot orifice or a draft blowing out the flame can also cause this. 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. Common issues are a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or a flow sensor that has gone bad. A contractor can diagnose which part is causing the fault code and replace it. Full replacement is usually only needed when the heat exchanger itself has cracked or corroded.
