Iron replaced lead in water pipes.
Lead pipes are not considered safe for use in plumbing systems because lead can leach into the water supply, posing health risks such as lead poisoning. It is recommended to replace lead pipes with safer alternatives.

Lead water pipes.
Lead is a heavy metal and poisonous to the human body. Use of lead pipes leads to a build up of lead in the system which affects the nervous system and can lead to brain damage and death.
Lead is malleable, corrosion-resistant, and has low melting point, making it suitable for use in water pipes.
Old water pipes and roof tiles are commonly made from lead, a metal that was widely used in plumbing and construction due to its malleability and resistance to corrosion. However, the use of lead has significantly declined due to health concerns associated with lead exposure, prompting the replacement of lead pipes and tiles with safer materials. Today, alternatives such as copper, PVC, and clay are more commonly used for these applications.
Sugar of lead refers to lead(II) acetate, a compound that was historically used to coat the inside of organ pipes to improve their tone quality. The lead acetate reacts with the sulfur compounds in the air to form lead sulfide, which created a smoother surface inside the pipes. However, the use of lead compounds in organ pipes has largely been discontinued due to health concerns related to lead exposure.

Lead pipes are made by melting lead and pouring it into molds to create the desired pipe shape. The molten lead is typically cast in sections, allowing for the creation of long, straight pipes. Once cooled and solidified, the pipes may undergo additional processes such as trimming or finishing to ensure they meet specifications. Historically, lead pipes were used in plumbing due to lead's malleability and resistance to corrosion, but their use has declined significantly due to health concerns associated with lead exposure.
If you refer to the composition, it is Lead (Latin: Plumbum). "Roman roofs used lead in conduits and drain pipes and some were also covered with lead, lead was also used for piping and for making baths" -Wikipedia
