Plumbing in Allentown, PA — What You Should Know
Allentown's Lehigh Valley housing stock is anchored by 1920s–1940s row homes and twin doubles with galvanized supply lines, cast-iron drains, and lead service connections that the city is still inventorying. Freeze-thaw cycles in the valley — sometimes 50 per winter — crack outdoor hose bibs and push frost lines deep enough to burst pipes in unheated row-home basements.
