What goes wrong in Anne Arundel County homes
1980s and 90s construction and polybutylene
31% 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.
Oil-heated homes
8% of occupied homes here heat with fuel oil, far above the national norm. Many of them make hot water with a tankless coil inside the boiler, which runs the boiler all summer. Plumbers often replace the coil with an indirect tank or a standalone water heater when the boiler is serviced or replaced.
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 Maryland winter those are the lines that freeze and split. See frozen and burst pipe repair.
