Local plumbing issues in Baltimore
Rowhouse plumbing
Old cast iron and galvanized pipe in rowhouses leak and clog.
Frozen pipes
Cold snaps freeze pipes in rear additions and exterior walls.
Basement backups
Heavy rain can back up old sewers into basements.
Rowhouse renovations
Many rowhouses have been renovated over decades, mixing old cast iron and galvanized pipe with newer PEX and PVC.
Water main breaks
Baltimore's aging water mains break regularly in winter, which can affect pressure and service lines.
Harbor neighborhoods
Low-lying harbor neighborhoods like Fells Point face tidal and storm flooding.
Basement laundry and drains
Rowhouse basements often hold the laundry and water heater beside an old floor drain, so a slow main line or failing heater floods the basement first.
