Polybutylene and Columbia's housing
The 1980–1999 share here is 45%, above the Maryland figure of 29%. That ranks 4th highest of the 34 Maryland cities we profile. Not every home from those years has polybutylene, but enough do that buyers, inspectors and insurers in Columbia ask about it.
Look for gray (sometimes blue or black) flexible pipe stamped PB2110 at the water heater, under sinks or at the main shutoff. Homes of the same era in nearby Laurel, Ellicott City, Catonsville raise the same question.
In Maryland: Basements and heavy storms make sump pumps and backwater valves common.
Permits

Repiping in Columbia: FAQ
Do insurers in Maryland ask about polybutylene?
Some do, and some limit coverage or charge more for homes that still have it. Ask your insurer directly, and keep any repipe invoice to show the pipe was replaced.
