Copper and galvanized pipes are safe and durable. However, as they age, costly problems may develop. The initial signs will be pinhole leaks in copper pipes, and lower water pressure and discolored water in galvanized pipes. Leaks can cause water damage and mold contamination throughout your property.
Galvanized pipes rust from the inside out much like a clogged artery, slowly strangling and contaminating your water supply. In many galvanized pipes, discolored poor-tasting water is a sign of problems. Higher water bills signal the possibility of leaks in areas that may not be visible, under slabs or underground. Once the leaks start, they tend to accelerate. Soon, the combination of increased water bills, plumbing repairs, property damage and loss of tenants or residents will exceed the cost of replacing the pipe. Property value will decrease, and chances are good that the replacement of pipe will be a precondition of a sale. It's a good idea to replace the pipes before the problems become too costly.
