Why Dundalk homes get repiped
68% of homes in Dundalk's covered ZIP codes were built before 1960 (68%, above the Maryland figure of 27%). That ranks 1st highest of the 34 Maryland cities we profile. Homes of that age were plumbed with galvanized steel, which rusts from the inside until pressure drops and the water runs brown.
Only 11% predates 1940, so most older homes here are postwar houses from the 1940s and 50s, typically one main run of galvanized pipe with branches to each fixture.
In Maryland: Older rowhouses in Baltimore and older suburbs have cast iron drains, galvanized lines and lead service lines.
