In the ol’ days of residential and commercial plumbing, the most common materials for piping were cast iron, clay, and galvanized steel. If you have a home that was built before 1970, you may have galvanized steel pipes in many places—if not for your entire plumbing system. Even earlier-built houses (pre-World War II) can have cast iron pipes and a clay sewer line.
These are outdated materials, and if your home contains any of them, we recommend calling our expert plumbers for whole-house repiping in Cincinnati, OH or wherever you are in our wide service area. The pipe materials we use to replace aging pipes are copper and different types of plastic.
