Lead pipes

The word, plumbing comes from lead pipes. A plumber was originally the one who worked lead to make plumbing installations. Since the 1970s, the use of lead pipes has been prohibited because they can cause health risks. They must be replaced by copper other pipes.

PEX pipes

PEX pipes (cross-linked polyethylene) are very strong, are not subject to corrosion and scaling and are used for hot and cold water supply. PEX pipes are sealed together with rings. They are not practical in plumbing installations with strong curves.
