Extreme Gulf Barrier Island Salt-Air Copper Corrosion on Tierra Verde
Tierra Verde sits on a Gulf barrier island adjacent to Fort DeSoto County Park, where salt-laden Gulf air attacks copper supply lines at a rate that is severe even by Florida coastal standards. The 1970s through 1990s homes along this island have copper that has been in this extreme salt-air environment for 35 to 55 years. Outdoor supply sections, hose bibs, pool equipment supply lines, and copper fittings at exterior walls on Tierra Verde face salt-air concentrations that can produce corrosion failures in outdoor copper in under 10 years of exposure -- a fraction of what the same pipe would last in an inland location. Interior slab copper at 35 to 55 years in this environment is also at active risk from the salt-air humidity that permeates the home. Blue-green staining, pinhole spray under sinks, and warm floor spots in slab homes are late-stage indicators that the supply system is failing broadly.
