Before copper and plastic pipes became available people used to use lead, iron or steel to make water pipes. Nowadays main water supply pipes for fresh water coming into buildings are made of plastic and pipes within buildings - delivering water to sinks, baths, showers and toilets - are made either of copper or plastic. Within buildings, pipes which take away waste water - which are also called drainage pipes - are usually made of plastic. Outside buildings, modern drainage pipes are mostly made of plastic but older drain pipes may be made of glazed earthenware (which is baked clay) or iron.

PVC pipes, made of combined plastic and vinyl, are often used for projects in which a drainage pipe has to hold up well against pressure and heavy weight. This type of drainage pipe can be constructed in a range of sizes and is very durable, even when exposed to chemicals.
Some drain cleaners wil harm plastic pipes if used excessively.
