What goes wrong in Franklin County homes
1980s and 90s construction and polybutylene
30% 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.
Mostly electric homes
72% of occupied homes here heat with electricity, and electric tank water heaters are the norm. Failed elements and thermostats are repairable, but tanks that leak need replacement. Heat pump water heaters are an efficient replacement where there's space and airflow.
Winter freezes
44% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Missouri winter those are the lines that freeze and split. See frozen and burst pipe repair.
Hard water
Missouri water is generally hard. With 72% of homes here on electric heat, scale on electric water heater elements is a frequent failure. See water softener installation.
