What’s different about water line repair in Boston
BWSC replacement programs
Program terms can affect cost and scheduling; checking first avoids paying for work a program might cover.
Undersized older services
Small-diameter service lines feeding multi-family homes limit flow when several units use water at once.
Homeowner checklist
- Check your address with BWSC
- Inspect the pipe entering the basement
- Note pressure drops when several fixtures run
Boston homes and when problems show up
Typical housing: Triple-deckers, brick row houses, Victorian single-families and converted multi-family buildings, plus newer condos in the Seaport and downtown.
- Winter: Insulate pipes in exterior walls, porches and basements; keep heat on in vacant units.
- Nor’easters: Coastal storms and heavy snow can cause power loss and frozen pipes; know your shutoffs.
- Spring thaw: Check sump pumps and basement drainage as snow melts.

Water Line Repair in Boston: questions
How can I tell if my Boston service line is lead?
Check BWSC records and the pipe at the meter: lead is soft, dull gray and turns shiny when scratched.
Will replacing my service line improve water pressure?
Often, yes, if the old line was corroded galvanized or undersized for the building.
Who is responsible for a leaking Boston service line?
The private portion from the curb or property line into the building is generally the owner’s responsibility; BWSC maintains the main and public portion.
