Galvanized supply lines corroding from the inside
Why it happens here
Galvanized supply was the standard in Harvey Park's 1950s ranches, early copper alongside it. The zinc wears away over decades and the steel rusts from the inside, so pressure drops, the water discolours, and pinhole leaks open behind walls — the whole cohort ages together. On nearly 4,000 homes built 1954–57, including about 170 by Cliff May, age is the first check.
Our approach
We pressure-test the system and route the repipe through basements and interior chases, preserving the mid-century fabric. Where corrosion is isolated, a section is replaced; where it runs through the house, a phased repipe is planned.
