Water Heater Repair in York, PA
Half of York's homes were built in 1939 or earlier, and two out of three heat with natural gas. That makes a gas water heater in an older basement the most common call here. If yours has stopped, is leaking or can't keep up, call now.
What shapes water heater trouble in York
Gas water heaters in older York homes
About 68% of York homes heat with natural gas, more than any other town we cover in the area, and the gas company here is Columbia Gas of Pennsylvania, not UGI. If your water heater runs on gas, pilot lights, thermocouples, gas valves and venting are the usual repairs.
In houses built before 1940, the heater often vents into an old masonry chimney. Cold weather and a weak draft can push air back down the flue and blow out the pilot. If the pilot keeps going out on cold, windy days, mention it when you call.
York water is soft to moderately hard
The York Water Company draws from the South and East Branches of the Codorus Creek. Its 2024 report puts hardness at about 4.97 grains per gallon (85 ppm), says it stays consistent year-round, and calls it the "transition range from soft to moderately hard."
That means less heavy scale than in harder-water towns, but sediment still settles in the tank over the years. A tank that pops or rumbles has buildup, and an older one that leaks from the bottom usually needs replacing rather than repair.
Rowhomes, shared walls and rentals
More than half of York homes are rented, and many are rowhomes with small utility spaces. A leaking tank in a rowhome can reach the neighbor's wall or ceiling fast, so close the cold water valve on top of the tank as soon as you see water.
Renters should tell the landlord or property manager first. Owners and landlords can call us directly for repair or replacement.
Safe steps for York homes

Who is the gas company in York, PA?
Columbia Gas of Pennsylvania lists York ZIP codes 17401 to 17408 in its service territory. If you smell gas, leave first, then call Columbia Gas at 1-888-460-4332 or 911 from outside.
Do I need a water softener in York to protect my heater?
The York Water Company describes its water as soft to moderately hard, about 5 grains per gallon. Many homes do fine without a softener for the heater alone. Your plumber can check the tank for sediment and advise.
Why does my pilot light keep going out in winter?
In older York homes the heater often vents into a masonry chimney. Cold air and a weak draft can blow the pilot out, and a worn thermocouple makes it worse. A plumber can test the thermocouple and check the venting.
Can you work on a water heater in a rowhome?
Yes. Tell us it's a rowhome and where the heater sits, so the plumber knows about access before arriving.
