Maryland licenses plumbers through a state board. In much of the state, permits come from the county or city.
In two suburban counties, WSSC Water supplies water and issues plumbing permits. Gaithersburg and Laurel are examples. Rockville runs its own system.
Half the homes in Baltimore were built before 1947. Rowhouses there often have original cast iron stacks and clay sewer lines.
In Anne Arundel County, many homes use county wells or private wells. Severna Park, Crofton and Annapolis are examples.
Freezing winters put pipes on outside walls at risk across the state.
In Montgomery County, Germantown and Silver Spring get WSSC Water. Columbia gets Howard County water, and Waldorf runs on Charles County wells.
