What goes wrong in Allegheny County homes

Pre-1960 homes: galvanized pipe and cast iron

55% of homes in Allegheny County's covered ZIP codes were built before 1960, 28% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.

Natural gas in most homes

80% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.

Long, hard winters

78% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Pennsylvania winter those are the lines that freeze and split. See frozen and burst pipe repair.
