Polybutylene and Potomac's housing
The 1980–1999 share here is 34%, above the Maryland figure of 29%. That ranks 12th 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 Potomac 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 Silver Spring, Rockville, Gaithersburg raise the same question.
In Maryland: Older rowhouses in Baltimore and older suburbs have cast iron drains, galvanized lines and lead service lines.
