Power outages hit your water heater hard here
Winter nights in Sanford average 16°F from December through February, and your water heater works to keep up with cold groundwater coming in. Over the last ten years the area has seen 95 winter storms and 93 damaging wind events, and in 2024 more than half of Maine households lost power for 24 hours or more.
When the power drops, an electric water heater stops heating until it comes back, and most units restart on their own once it does. Gas water heaters with a standing pilot keep running through the outage, but if a storm knocks the pilot out, it will not relight itself. Either way, a long outage followed by a hard restart puts strain on a heating element or a thermocouple that was already near the end of its life, and that is often when it gives out for good.

- Why is my water heater leaking from the bottom?
- The most common reason is that the tank itself has corroded through and is failing. Water heaters have a glass or ceramic lining inside the steel tank, and once that lining cracks, the metal underneath rusts and eventually lets water seep out at a seam or fitting near the bottom. A loose drain valve or a failing temperature and pressure relief valve can also drip water down the side of the tank, so it can look like a bottom leak even when it isn't. Once a tank itself is leaking, it needs to be replaced, not patched, because the tank will keep corroding.
- Why won't the pilot light on my water heater stay lit?
- Usually it means the thermocouple isn't sensing the flame and is shutting off the gas as a safety measure. The thermocouple is a small sensor that sits in the pilot flame and tells the gas valve the flame is lit. When it wears out or gets coated in soot, it can't confirm the flame anymore, so the valve cuts the gas and the pilot goes out. A weak or dirty pilot orifice, or a draft reaching the pilot, can cause the same thing. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, mineral scale built up on the heat exchanger, a failed igniter, or an error code pointing to a sensor. Tankless units run hotter and more efficiently than tank models, but that heat exchanger is also the part most affected by hard water, so scale buildup is one of the more frequent repairs. A contractor can flush the system or replace the failed part rather than the whole unit in most cases.
