True or False: Galvanized iron pipes are becoming less popular due to their tendency to corrode more quickly.

Galvanized iron pipes are indeed becoming less popular, and the statement is true due to their susceptibility to corrosion over time. While they start off with a protective zinc coating that helps prevent rust and corrosion, this coating can wear away, especially when exposed to moisture and various chemicals. As the internal surface of the pipe begins to corrode, this not only reduces the pipe's lifespan but can also lead to contamination of the water supply and reduced water pressure due to blockages from corrosion products.

With the advancements in plumbing materials, such as PVC, PEX, and copper, which offer better durability and resistance to corrosion, many builders and contractors are opting for these newer materials. This shift reflects a growing awareness of the long-term issues associated with galvanized pipes, contributing to their decline in popularity.
