Cold winters and storm outages both hit your water heater here
Murrysville needs heat eight months of the year, October through May, and winter nights average 23°F from December through February. Water entering your tank runs cold that whole stretch, so the burner or element has to work longer to bring it up to temperature. That extra runtime wears on the parts that do the heating, and it is often why a water heater that struggled through one winter fails outright the next.
Storms add another problem. Westmoreland County has logged 29 winter storms and 441 damaging wind events over the past ten years, and 15% of Pennsylvania households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition, or an electric tank, goes cold until the power comes back on.

A new water heater would cut about $70 a year off hot water for a typical Pennsylvania home.

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 cause is the tank itself failing from the inside, where years of sediment and rust eat through the steel until water seeps out at a seam or the bottom. It can also be a loose drain valve or a fitting that has just worked itself loose over time, which is worth checking before you assume the worst. A failing temperature and pressure relief valve can leak from the bottom too, especially if it drains down the side of the tank to the floor. Once a tank itself is leaking, it needs to be replaced, not patched, so a contractor will want to look at where the water is actually coming from before saying which one you have.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer sense that the pilot is lit, so it shuts the gas off as a safety measure. A dirty or clogged pilot orifice can cause the same problem by starving the flame until it goes out. A draft reaching the pilot from a nearby vent or a gap around the water heater can also blow it out repeatedly. A standing pilot like this runs without any electricity, so a power outage is never the cause. A contractor can test the thermocouple and clean or adjust the pilot assembly to fix it.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable, including a failed igniter, a bad flow sensor, or a heat exchanger clogged with mineral scale. Scale buildup is especially common if the unit has never been descaled, since it restricts flow and can trigger error codes or reduce hot water output. A contractor can run the unit's diagnostics to read the error code and pinpoint which part is failing before recommending a repair. Full replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
