Pre-1940 houses carry galvanized steel water lines, cast-iron drains and clay sewer pipe unless someone has replaced them. Partial repipes leave mixed materials behind, and the joints between old and new pipe are common leak points. For 21230, that points first to galvanized water lines, cracked cast-iron drains and burst supply pipes.
Rowhouses and townhouses make up 62% of homes in 21230. Row homes share party walls, so water from a burst pipe travels into the house next door, and in most row homes the water line enters through the front basement wall from the meter out front.

Where is the main water shut-off in a 21230 rowhouse?
In a Baltimore rowhouse, the main shut-off valve is usually on the basement wall facing the street, where the water line comes in from the meter at the curb. The meter and valves in the curb vault are City equipment; call 311 when the water has to be shut off there.
Is a leak in 21230 your pipe or the utility’s?
The property owner is responsible for the service line from the water meter into the house; the Baltimore City Department of Public Works maintains the line to the meter vault, or to the property line where there is no vault. Report water running in the street, a leaking hydrant or a main break to Baltimore City 311 (call 311 or use the 311 app). A leak between the meter and your foundation, or anywhere inside, is a job for a plumber.
