Galvanized supply lines corroding from the inside
Why it happens here
The 1950s brick ranches in University Hills run on galvanized steel supply, with early copper in places. Over decades the zinc coating wears away and the steel rusts from the inside out, so pressure drops, water discolours and pinhole leaks start behind walls — and with full, often finished, basements, the leaks hide longer.
Our approach
We pressure-test the system in University Hills, where a 1950s brick ranch with a finished basement hides its supply lines behind finished walls, so the test decides the scope before anything is opened. Where corrosion is isolated, we replace that section; where it runs through the house, we plan a phased repipe and show the pressure readings before and after.
