Cold water and winter outages both work against your water heater
Water heaters in New Bedford work harder from October through May, when the water coming in off the street is cold and the tank has to make up more ground before anything hot reaches the tap. That extra work adds hours onto the heating element or burner, and a weak element or worn burner tends to give out right in the middle of that stretch, not in summer.
Bristol County also gets real winter weather, with 36 winter storms and 282 damaging wind events recorded over the past ten years. Statewide, one in ten households lost power for at least 24 hours in 2024. An electric water heater will not heat water without power, and a gas unit with an electric igniter will not light either. A standing pilot keeps running through an outage, since it does not need power at all.

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 that the tank itself has rusted through and is failing. Water heater tanks have a glass lining inside, and once that lining cracks, the steel underneath rusts until it gives way. A leak coming from the bottom of the tank means the tank needs to be replaced, not repaired, since there is no way to seal it. If the water is actually coming from a fitting or the drain valve, a contractor can check that first, since those can sometimes be tightened or replaced without touching the tank.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. The thermocouple is a small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. When it fails, the gas valve shuts off the pilot as a safety measure even though the flame was burning fine. A dirty or partly blocked pilot orifice can cause the same symptom, so a contractor will usually check both before replacing anything. If it keeps going out, it is worth having someone look at it rather than relighting it over and over.
- Can a tankless water heater be repaired?
- Yes, tankless water heaters are built to be serviced rather than replaced when something goes wrong. Common issues are a scaled up heat exchanger, a failed igniter, or a blocked vent, and a contractor can clean or replace any of those parts. Tankless units also display error codes that point to the specific problem, which makes diagnosis faster than with a tank unit. Regular descaling helps keep the heat exchanger from scaling up again.
