Copper v plastic pipe: the pros and cons

Pipes can be made from a variety of different materials, each with their own advantages and disadvantages. Choosing which is most appropriate for your needs depends upon the pipe’s intended purpose, but also other factors such as cost. Copper is a traditional option, but plastic is becoming increasingly popular.

Copper Pipes

Copper is a quintessential plumbing material, with a history dating back to Ancient Egypt. It is a strong and effective conduit for water, air, gas, steam, oil and more, with an average lifespan of 25 years. Copper pipe connectors such as those available at watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems/ come in a range of sizes for different systems.

Another particular advantage associated with copper is its antimicrobial properties. It is less likely to become contaminated with bacteria and other potentially harmful substances. Copper can withstand higher temperatures than plastic, but it can be more easily damaged by extreme cold, whilst its ability to withstand pressure depends on the exact nature of the fitting.

The main problem with copper is that it is expensive, plus its weight and rigidity make it more difficult and time-consuming to install.

Plastic pipes

Plastic pipes are highly durable, lasting for 50 years or longer without corrosion. In colder weather, they can expand as many as eight times without splitting or becoming brittle.

Plastic is also a more lightweight and versatile option than copper, able to be adapted to smaller or more awkwardly shaped areas. A plastic fitting can be connected within seconds, making it highly time-efficient. Perhaps most significantly, it is highly cost effective, though the price of installation can cause the overall bill to rise.

Plastic is an area of continued innovation, meaning it may become even more effective in future, but the production process does create sustainability concerns.

Many plumbers have their own preferences about which type of pipe they prefer to use, but you need to consider your own particular circumstances before you make any final decision. Both copper and plastic have their own benefits, but also their own disadvantages. You should carefully consider all the factors.
