Lyijyjohtimet, or lead pipes, are pipes used for conveying water in plumbing systems. They are typically made from lead, a soft, malleable, and heavy metal. Lead pipes were commonly used in the past due to their durability and resistance to corrosion. However, their use has significantly declined in recent decades due to health concerns.

Lead can leach into drinking water, particularly in older homes where the pipes may be more prone to corrosion. Prolonged exposure to lead in drinking water has been linked to various health issues, including developmental problems in children, neurological disorders, and kidney damage. As a result, many countries and organizations have recommended or mandated the replacement of lead pipes with materials that are less likely to leach harmful substances, such as copper, PVC, or PEX.

The replacement of lead pipes is often part of broader infrastructure improvements aimed at enhancing public health and safety. In some cases, lead pipes are still used in specific applications where their properties are advantageous, but these instances are increasingly rare. The transition away from lead pipes reflects a broader trend in plumbing and construction towards materials that are safer and more environmentally friendly.
