There are advantages and disadvantages to both copper and PVC pipes, and the right choice will depend on factors such as budget, application and requirement for durability. Here we take a look at the two different types.
Copper Pipe
Copper pipe is widely available from companies such as https://watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems and has been used for plumbing applications for many years. They are commonly used in water supply lines but may also be found in older properties.
Copper pipe offers a high level of reliability and durability and can last for up to 80 years. These pipes are resistant to high temperatures, making them ideal for use in hot water supply lines. They will not degrade easily and can resist most household chemicals. Other benefits of copper pipes include the fact that they are generally considered more environmentally friendly and will not release toxic fumes in the event of a fire, for example.
The downside of copper pipe is that pinhole leaks can occur, and these can be hard to stop at an early stage. Copper pipe is also more expensive than PVC, although the reliability and durability offered can make up for this if your budget allows.
PVC Pipe
Polyvinyl chloride or PVC piping is most commonly used in sewage and drainage systems. It is an affordable and easy to install option and may be more reliable than copper piping for drainage systems due to its corrosion resistance to acidic water.
PVC pipes are lightweight and are a popular choice for DIY projects. They do not freeze as easily as copper pipes in very cold weather, making cracking less likely, and offer reliability thanks to their abrasion and corrosion resistance.
Overall, PVC does not offer the same durability as copper pipe, however. The material can last longer, but cement solvent joints in PVC piping will deteriorate over time, and this can lead to leaks and water damage. PVC is also not as suitable for hot water systems, and pipes are usually thicker, making them more difficult to put into tight spaces.
