Maryland plumbing FAQ
How do I check a plumber's license in Maryland?
The Maryland State Board of Plumbing licenses plumbers and gas fitters; check a license through the Maryland Department of Labor.
Do pipes freeze in Maryland?
Yes, during cold snaps. Pipes in crawl spaces, exterior walls and unheated garages are the ones that freeze. Disconnect hoses in fall and open sink cabinets on the coldest nights.
Is Maryland water hard?
Generally moderate, based on national hardness mapping, but it varies by utility and by well. Your water provider's annual water quality report lists the hardness for your system, and a plumber can test well water.
How old are homes in Maryland?
Census estimates for Maryland put 27% of homes as built before 1960, 25% from 1960 to 1979, 29% from 1980 to 1999 and 20% in 2000 or later. Older homes are more likely to have galvanized supply pipe and cast iron or clay sewer lines.
