Cast Iron Pipe Damage in Florida. If you own a home, in the Miami area, that was built before 1975, you probably have cast iron pipes. When cast iron pipes in South Florida soil come into contact with what runs through waste lines rusting and corrosion are accelerated. This is because of the makeup of the soil, which is particularly moist, and has high salinity levels.
The limited lifespan of cast iron pipes is a fact of life wherever you may reside. However, here in South Florida, the corrosion and deterioration typically starts to set in more rapidly. As the water escapes, it can erode and contaminate the underlying soil. This can eventually cause a total pipe collapse.
