What Washington County winters do to a water heater
Groundwater coming into your house is cold most of the year here, and from December through February, nights averaging 23°F push it colder still. Your water heater has to work harder to make up that difference, and the burner or heating element runs longer to do it. That extra run time wears on the thermostat and the heating element in an electric unit, or the burner and igniter in a gas one.
The county has seen 263 damaging wind events and 10 winter storms over the past ten years, and storms like that knock out power. Statewide, 15% of Pennsylvania households lost power for 24 hours or more in 2024. An electric water heater does nothing until the power is back, and when it returns, some units need the reset button pressed before they will heat again. A gas water heater with a standing pilot keeps working through an outage, but one with an electronic ignition will not light until it has power.

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?
- Water pooling under the tank usually means the tank itself has rusted through from the inside. Once that happens, the tank can't be patched or resealed, because the rust has already broken the metal. Sometimes what looks like a tank leak is actually the drain valve or a loose fitting on top, so a contractor will check those first before writing off the tank. If it is the tank, replacement is the only fix.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and isn't sending the signal that tells the gas valve to stay open. It's a small part next to the pilot flame, and it degrades with age like any other part exposed to constant heat. A weak pilot flame or a draft in the area can cause the same symptom, so a contractor will check both before replacing anything. This is a repair, not something that means the water heater needs to be replaced.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Common issues are a clogged inlet filter, mineral buildup on the heat exchanger, or a failed igniter, and all of those can be serviced without replacing the unit. Hard water speeds up the buildup problem, so units that haven't been descaled in a while are more likely to need that service. A contractor can run the error code the unit is showing and tell you which of these it is.
