Metals that react readily with water:
* Sodium, potassium, calcium, magnesium: These metals react violently with water, producing hydrogen gas and heat. They are definitely not suitable for water pipes.
* Iron: Iron rusts when exposed to water and oxygen. While iron pipes have been used historically, they can corrode and contaminate the water with iron.
* Copper: Copper can react with water, especially in the presence of oxygen, forming a layer of copper oxide. This can affect the taste and color of the water.
Metals commonly used for water pipes:
* Copper: Despite its potential for reacting with water, copper is still widely used for water pipes because of its durability and resistance to corrosion.
* PVC (Polyvinyl chloride): PVC is a plastic material that is highly resistant to corrosion and is commonly used for water pipes.
* PEX (Cross-linked polyethylene): PEX is another type of plastic that is becoming increasingly popular for water pipes due to its flexibility and resistance to corrosion.
* Stainless steel: Certain grades of stainless steel are resistant to corrosion and are suitable for water pipes, although they are generally more expensive than other options.
* Galvanized steel: Steel coated with zinc (galvanized) provides some protection against rusting and is still used for water pipes in some applications.
Important Note: Even metals that are considered suitable for water pipes can corrode over time, depending on factors like water quality and the presence of other metals.
