This is what years of buildup can look like inside a commercial cast-iron drain line.
ADR evaluated three 4-inch sanitary lines at a St. Rose property—approximately 184 feet total. Camera evidence showed heavy internal deposits and a restricted opening, so the project required mechanical descaling, flushing, and another camera verification before rehabilitation planning.
The lesson: restoring flow is not the same as proving the pipe is healthy.
