York County winters are hard on a water heater
Your water heater works harder from October through May, when incoming groundwater runs coldest and the tank has to make up more ground to hit your set temperature. That extra runtime wears on the heating element or the burner, and it shows up as water that never quite gets hot enough, or takes longer than it used to.
Winter here also brings power out with it. Pennsylvania saw 15% of households lose power for a day or more in 2024, and York County has logged 15 winter storms and 205 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep running through an outage. One with electronic ignition will not fire back up until the power does, and if yours does not come back on by itself once it's restored, that's a sign the ignition system needs a look.

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?
- Most often the tank itself has rusted through and is starting to fail. Water heaters corrode from the inside over years of use, and once the tank is breached, no fitting or valve can be tightened to stop it. It can also be a loose drain valve or a fitting that has worked itself loose, which a contractor can check before assuming the tank is done. If the leak is coming from the tank wall itself, the unit needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is usually the cause. It is the small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. Once it wears out or sits out of position, the valve shuts the gas off as a safety measure, and the pilot won't hold. A dirty pilot orifice or a draft can also blow the flame out, so a contractor can tell you which one it is by testing the thermocouple directly.
- Can a tankless water heater be repaired?
- Yes, most tankless problems come down to parts that can be replaced without swapping the whole unit. The igniter, the flow sensor, and the heat exchanger are the parts that fail most, and any of them can be serviced on its own. Mineral buildup on the heat exchanger is common too, especially in a unit that has never been descaled, and flushing it often restores flow and heat. A contractor can open the unit and tell you which part is at fault.
