Final answer:
The question pertains to lead-poisoning prevention by replacing lead water pipes with copper pipes. It discusses the advantages of copper as a durable and safe material for plumbing that does not easily corrode or leach substances into the water supply.
Step-by-step explanation:
The question primarily deals with the issue of lead poisoning due to water pipes made of lead. Replacing them with copper pipes is suggested by a plumber to prevent any health hazards. While copper is a better choice than lead for water pipes, because it does not leach into the water as readily and thus lowers the risk of lead poisoning, the substantial part of the question discusses the different materials used for pipes and hazards associated with them.
In deciding to replace your lead pipes with copper, you are making a health-conscious choice. Copper is known for its durability and resistance to corrosion, which makes it a safe material for water pipes. A plumber offering to use up his supply of copper pipe for a low cost could provide a good opportunity to upgrade your system while minimizing expenses.
