Rust and corrosion can be a real issue for plumbing systems as they age. Corrosion can cause both leaks and can also lead to clogs. Watch out for spots or other forms of corrosion on your pipes, which may indicate that you need to have them looked at by a professional plumber right away! If the problem appears more severe than it is, consider replacing any pipes with high risk factors- like ones made from cast iron – because over time these will only get worse and require significant repairs later. Corrosion also happens under the home, inside the concrete slabs or in dirt if the pipes covering has broken down. Concrete and dirt will chemically react with the metal causing the pipes to break down. Pipe corrosion is one of the leading causes of a slab leak.
