Cold groundwater and hard winters wear on a water heater here
Water heaters in Worcester County work against cold incoming water for eight months of the year, October through May. The colder that water is, the longer the burner or the heating element has to run to bring it up to temperature, and the more that cycle repeats, the more it wears on the thermostat and the heating element itself.
Winter nights averaging 18°F also mean basements and utility closets run cold, and a gas water heater's pilot or igniter has to work harder in that cold to light reliably. The county has seen 71 winter storms and 427 damaging wind events over the past ten years, and storms like these knock out power. Most gas water heaters with a standing pilot keep working through an outage, but ones with electric ignition will not light until power is back, and an electric water heater simply stops heating until it is.

- Why is my water heater leaking from the bottom?
- The tank itself has likely rusted through and started to fail. Water heaters corrode from the inside over the years, and once the tank wall gives way, the leak will not stop or seal itself. It could also be the drain valve or a fitting on the bottom, which a contractor can check before assuming the tank is done. If the tank is the source, the unit needs replacement, not repair.
- 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 shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft blowing out the flame can also be the cause. A contractor can test the thermocouple and clean or replace whatever part is failing.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues a contractor can diagnose and fix without replacing the unit. A contractor can flush the exchanger and test the parts to tell you whether repair makes sense or if the unit has reached the end of its life.
