What goes wrong in Warren County homes
Newer homes on their first water heater
38% 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
28% 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.
Winter freezes
34% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Kentucky winter those are the lines that freeze and split. See frozen and burst pipe repair.
Hard water
Kentucky water is generally hard. With 57% of homes here on electric heat, scale on electric water heater elements is a frequent failure, and newer homes with tankless heaters need yearly descaling. See water softener installation.
