Water pipe

Water pipe is a pipe or tube, frequently made of plastic or metal, that carries pressurized and treated fresh water to a building (as part of a municipal water system), as well as inside the building.

History

The history of water pipes dates back to the ancient civilizations. The Indus Valley Civilization in 2700 B.C. used earthen plumbing pipes with broad flanges for waste water disposal. In the ancient Greek city of Knossos on the island of Crete, archaeologists have discovered four different types of water pipes: baked clay pipes, stone pipes, bronze pipes, and lead pipes.

Types of Water Pipes

There are several types of water pipes used in modern plumbing systems, including:

• Copper Pipes: These are traditionally used for their corrosion resistance, thermal conductivity, and durability. However, they are relatively expensive.

• PVC Pipes: These are popular for their affordability and ease of installation. They are typically used for drain, waste, and vent pipes.

• PEX Pipes: These are flexible plastic pipes that are becoming more popular in residential plumbing systems. They are easy to install and resistant to both freezing and high heat.

• Galvanized Steel Pipes: These were commonly used in homes built before 1960. They are prone to corrosion and are being phased out in favor of PEX and copper pipes.

Health Concerns

There are some health concerns associated with certain types of water pipes. For example, lead pipes, which were commonly used in the early 20th century, can leach lead into the water supply, which can cause serious health problems. Similarly, PVC pipes can leach vinyl chloride, a known carcinogen, into the water.
