Galvanized pipes, once a standard in residential plumbing, present challenges in older properties due to their construction and inherent susceptibility to corrosion. These pipes are steel pipes coated with a layer of zinc to prevent rusting. However, this zinc coating degrades over time, leading to internal corrosion and the buildup of mineral deposits. As an example, water pressure may diminish noticeably as the pipe diameter narrows due to the accumulation of scale on the interior walls.
The implications of using this type of plumbing are significant. The deterioration of the zinc coating not only reduces water flow but also introduces lead and other heavy metals into the water supply. This poses a serious health risk, especially for vulnerable populations like children and the elderly. Historically, galvanized pipes were favored for their durability relative to other materials available at the time; however, their lifespan and impact on water quality render them a liability as they age.
