What goes wrong in Oswego homes

Natural gas in most homes

90% 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.

Newer homes on their first water heater

47% of homes here were built in 2000 or later. Those houses usually have PEX or CPVC supply lines in good shape, so the work is on equipment: original tank water heaters past their 8 to 12 year service life, expansion tanks, pressure regulators and fixtures. See water heater replacement.

1980s and 90s construction and polybutylene

33% of homes were built between 1980 and 1999. Polybutylene supply pipe was installed widely in US homes from about 1978 to 1995, so houses from these years are worth checking for gray plastic pipe stamped PB2110, usually visible at the water heater or under sinks. Insurers and buyers often ask about it. See polybutylene replacement.

Long, hard winters

20% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Illinois winter those are the lines that freeze and split. See frozen and burst pipe repair.
