What goes wrong in Johnson County homes
1980s and 90s construction and polybutylene
32% 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.
Natural gas in most homes
62% 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
36% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Indiana winter those are the lines that freeze and split. See frozen and burst pipe repair.
Hard water
Indiana water is generally hard. With 62% of homes here on gas, scale settles as sediment in gas water heater tanks, which then rumble and wear out early. See water softener installation.
