Galvanized supply lines corroding from the inside
Why it happens here
one of Denver’s oldest working-class stocks keeps bringing it up here. Pressure drops, water discolours, and pinhole leaks start behind walls. Most Elyria-Swansea homes built before 1900 used galvanized steel supply lines. Over a century the zinc coating wears away and the steel rusts from the inside out.
Our approach
We pressure-test the system and, where the corrosion is isolated, replace that section. Where it runs through the house, we plan a repipe and show the pressure readings before and after.
