Philadelphia, Pennsylvania – As the winter solstice arrives this Sunday, colder overnight temperatures across Pennsylvania are increasing the risk of frozen pipes, putting homes and businesses in Philadelphia on alert for potential water damage. The combination of long winter nights and sustained cold creates prime conditions for pipes to freeze and burst if precautions are not taken.
According to the National Weather Service and the Pennsylvania State Fire Marshal, pipes located in unheated basements, crawl spaces, attics, and exterior walls are most vulnerable when temperatures remain below freezing for several hours. When frozen pipes thaw, pressure can cause cracks that lead to rapid flooding inside homes.
In Philadelphia, aging infrastructure and tightly packed rowhomes can amplify the risk, especially where plumbing runs along exterior walls. Officials recommend insulating exposed pipes, sealing gaps around vents and doors, and keeping indoor temperatures at or above 55 degrees, even when residents are away. Allowing faucets to drip slightly overnight can also help prevent freezing.
Fire officials strongly warn against using torches, open flames, or space heaters to thaw frozen pipes due to the high fire risk. If a leak is suspected, residents should shut off the main water valve immediately.
Cold conditions are expected to linger into early next week, and additional winter safety advisories may be issued as the season settles in across the region.
