Local context: Boston gets some of the softest water in the US from the Quabbin and Wachusett Reservoirs (20–30 ppm). Despite soft water, the city's extreme age — median housing year built before 1950 — means lead service lines are still present in tens of thousands of properties.
Plumber pricing in Boston depends on job type, time of day, and whether work is flat-rate or hourly. Most homeowners in Suffolk County pay $225–$725 for a standard service call and repair. Bigger jobs — water heater, sewer line — are significantly more.
