Copper and plastic pipes have been compared and contrasted for decades, with both materials offering unique advantages and disadvantages. While copper pipes have been used for centuries and are known for their durability, plastic pipes have gained popularity due to their lower cost and quicker installation process.
One notable difference between the two materials is their noise level. Plastic pipes are quieter than copper pipes, especially when used with high-pressure water systems or when water is rushing through the pipes. The flexibility of plastic pipes contributes to their quieter nature, as they are less likely to transmit vibrations and sounds throughout the plumbing system.
The quietness of plastic pipes can be advantageous in certain settings, such as in homes where quiet environments are preferred. The reduced noise level can create a more peaceful and relaxing atmosphere. Additionally, in commercial or industrial spaces where machinery or equipment may be in use, plastic pipes can help minimize background noise, making it easier to work or communicate.
Furthermore, the quietness of plastic pipes can also be beneficial in plumbing applications where noise transmission needs to be minimized. For example, in multi-story buildings or apartments, using plastic pipes can help prevent noise from travelling between floors or units, providing a more pleasant living experience for residents.
While plastic pipes offer the advantage of being quieter, it is important to consider other factors when choosing between plastic and copper pipes. For example, copper pipes are known for their durability, longevity, and ability to withstand high temperatures. On the other hand, plastic pipes may be more susceptible to damage and have a shorter lifespan, but they are flexible, corrosion-resistant, and easier to install. Ultimately, the choice between plastic and copper pipes depends on specific requirements, budget, and personal preferences.

Plastic pipes are cheaper and easier to install
Plastic pipes are generally cheaper and easier to install than copper pipes. The cost of copper pipes has risen substantially due to its increased recycle value, making plastic pipes a more affordable option for many. Plastic pipes are also lightweight, flexible, and quick to assemble, making them easier and faster to install than copper pipes.
The flexibility of plastic pipes allows them to be cut and fitted more easily than copper pipes, which are rigid and need to be cut to the correct size during installation. Plastic pipes can be snaked through finished walls without removing drywall, whereas copper pipes require the removal of drywall to make connections. Additionally, copper pipes require elbow fittings at every corner, resulting in more installation work.
The lightweight nature of plastic pipes also makes them more affordable to handle and transport than copper pipes. This is especially advantageous for large-scale projects, where plastic pipes are often preferred due to their lower startup costs.
While copper pipes have their advantages, such as durability and aesthetics, plastic pipes offer a cost-effective and convenient alternative. The ease and speed of installation of plastic pipes can result in significant savings for plumbers and homeowners.
However, it is important to note that plastic pipes may not be suitable for all situations. They are less flexible at the joints, bulkier, and not recommended for use with hot water or in areas with high UV light exposure. Nonetheless, plastic pipes remain a popular choice due to their affordability and ease of installation.

Copper pipes are more durable and long-lasting
Copper's durability stems from its ability to withstand high and low temperatures without losing its strength. This thermal resistance allows copper pipes to be embedded in concrete during installation and makes them suitable for supplying cold and hot water. In contrast, plastic pipes are not always suitable for boiling water as they release dangerous chemicals when overheated, and they can warp when exposed to hot water. Additionally, long-term exposure to ultraviolet light degrades plastic, making it more susceptible to damage over time.
Copper pipes are also less susceptible to damage caused by rodents, as mice and rats are known to chew on plastic piping. Copper pipes are also naturally anti-microbial, inhibiting the growth of bacteria and other microorganisms. This quality is why ships' bases are coated in copper to prevent the growth of organisms like barnacles.
While copper pipes may be more challenging to install due to their weight and rigidity, their durability and longevity make them a more reliable choice in the long run. This is especially true in certain regions, like the San Andreas fault line in California, where copper pipes are recommended due to their superior durability.
