What goes wrong in Berkeley County homes
Newer homes on their first water heater
41% 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.
Mostly electric homes
76% 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.
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.
Winter freezes
29% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold West Virginia winter those are the lines that freeze and split. See frozen and burst pipe repair.
