Back Bay Brownstones

Back Bay’s historic brownstones often retain original cast-iron risers dating to the late 19th century. Over decades, minor corrosion creates microscopic perforations—too small to trigger leaks but enough to draw air into drainlines, causing gurgling or reduced flow. Standard high-volume flushes can accelerate degradation by agitating mineral-rich Boston water deposits. Targeted low-pressure flushing with controlled flow rates prevents erosion while preserving pipe integrity. This requires flow meters, not guesswork, to avoid worsening latent weaknesses.
