Old Home, New Pipes: Drain Challenges in North

Owners of historic homes on Chicago’s North Shore—particularly in towns like Evanston, Wilmette, Winnetka, and Glencoe—are increasingly confronting a familiar problem: the drain lines beneath their properties were built for another era. As fixtures, laundry loads, and water use patterns have evolved, many older systems are struggling to keep up, leading to slow drains, recurring backups, and costly emergency repairs.

While drainage issues can appear “random,” plumbing professionals say they often trace back to predictable limitations of older materials and layouts. In many cases, the piping itself is still physically present, but performance has declined over decades due to corrosion, settlement, and buildup inside the pipe.
