Plumbing conditions in Maryland
Maryland has humid summers, cold winters and coastal storms on the Chesapeake Bay. Baltimore rowhomes, mid-century suburbs with basements, and bay-front homes exposed to tidal flooding.
Maryland gets real cold snaps most winters. They are short, which is exactly why homeowners get caught out: hose bibs left connected, pipes along outside walls and uninsulated crawl-space lines are the usual failures.
Water hardness in Maryland is moderate in most systems, so scale is a slow, long-term issue rather than a constant one. Private wells vary widely and are worth testing.
