Thousands of homeowners across the country consider copper repipe to fix and replace defective or leaking pipes. Many older homes and commercial buildings, particularly those built before 1970, had the original plumbing constructed with galvanized piping- iron pipes coated in zinc. As the zinc wears away, it causes a range of problems, including corrosion and rust. Rusty buildup can contribute to low water pressure and can discolor the water. Additionally, rusted and corroded piping can cause poor transfer of hot water- this explains why a person might suddenly experience a burst of freezing cold water during a shower if someone else in the house decided to run the washing machine or dishwasher. Even worse still, the corrosion caused by galvanized piping can eventually lead to drastic leaks, which can cause water damage elsewhere and end up being a very costly outcome!
