Polybutylene and Frederick's housing
The 1980–1999 share here is 35%, above the Maryland figure of 29%. That ranks 10th 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 Frederick 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.
In Maryland: Older rowhouses in Baltimore and older suburbs have cast iron drains, galvanized lines and lead service lines.

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.
