Why Cast Iron Pipes Corrode in Denver
Several factors in Denver contribute to pipe corrosion:
Water chemistry – Minerals in Denver’s water speed up rusting.
Soil conditions – Expansive clay soils and shifting ground put pressure on underground pipes.
Age – Cast iron typically lasts 50–75 years. Homes built before 1970 are at risk.
Oxidation – Metal reacts with moisture, causing rust and scaling inside the pipes.

Backups in toilets, tubs, or floor drains
Brown or discolored water
