Baltimore's rowhouses were built during an era when cast iron was the standard material for drain waste and vent systems. These pipes last 50 to 75 years under ideal conditions, but Baltimore's humid climate and freeze-thaw cycles accelerate interior corrosion. As rust scale builds up inside the pipe, the effective diameter shrinks, reducing flow capacity and increasing the risk of clogs. When you flush a toilet in a home with corroded drain lines, even small obstructions can cause complete blockages and overflows. Regular camera inspections catch this deterioration early, before an emergency happens.
