Comparing Copper Vs PEX Pipes Pros And Cons

When it comes to plumbing, two popular choices for pipes are copper and PEX. Both materials have their own set of advantages and disadvantages, making it essential to understand the pros and cons of each before making a decision. In this article, we will delve into the world of plumbing pipes and explore the differences between copper and PEX, weighing their pros and cons to help you make an informed choice. So, let’s dive in and explore the world of copper vs PEX pipes!


Copper Pipes: Pros and Cons

Copper pipes have been the go-to choice for many years due to their durability and reliability. Let’s take a closer look at the pros and cons of copper pipes.

Pros of Copper Pipes

  1. Durability: Copper pipes are known for their longevity. They can withstand high pressure and extreme temperatures, making them suitable for both hot and cold water applications.
  2. Resistance to Corrosion: Copper is resistant to corrosion, making it an excellent choice for areas with aggressive water conditions or acidic soil. This resistance ensures the longevity of the pipes and prevents leaks.
  3. Environmentally Friendly: Copper is a natural material that can be recycled, making it an eco-friendly option for plumbing systems.
  4. Safe and Healthy: Copper pipes do not release harmful chemicals into the water, ensuring the safety and health of the occupants.

Cons of Copper Pipes

  1. Higher Cost: Copper pipes tend to be more expensive than PEX pipes. The cost of copper itself, along with the additional labor required for installation, can increase the overall expense.
  2. Prone to Theft: Copper pipes have a higher risk of theft due to their scrap value. This can be a concern, especially in unoccupied buildings or areas with a high crime rate.

PEX Pipes: Pros and Cons

PEX, short for cross-linked polyethylene, is a newer alternative to copper pipes. Let’s explore the pros and cons of PEX pipes.

Pros of PEX Pipes

  1. Flexibility: PEX pipes are highly flexible, allowing for easy installation around corners and obstacles. This flexibility reduces the need for additional fittings, minimizing the risk of leaks.
  2. Cost-Effective: PEX pipes are generally less expensive than copper pipes. The lower material cost, combined with the ease of installation, can result in significant cost savings.
  3. Resistance to Freeze Breakage: PEX pipes have the ability to expand and contract, making them more resistant to freeze breakage compared to rigid copper pipes.
  4. Quieter Operation: PEX pipes are known for their quiet operation, as they absorb and reduce water hammer noises.

Cons of PEX Pipes

  1. Susceptible to UV Damage: PEX pipes are not suitable for outdoor use or exposure to direct sunlight, as they can degrade when exposed to UV rays.
  2. Limited Longevity: While PEX pipes have a lifespan of around 40-50 years, this is generally shorter than the lifespan of copper pipes.
  3. Not Suitable for High Temperatures: PEX pipes have temperature limitations, making them unsuitable for certain applications, such as hot water supply lines in commercial kitchens.


Q: Which is more cost-effective, copper or PEX pipes?

A: PEX pipes are generally more cost-effective due to their lower material cost and ease of installation.

Q: Are copper pipes more durable than PEX pipes?

A: Yes, copper pipes are known for their durability and longevity, making them a reliable choice for plumbing systems.

Q: Can PEX pipes be used for outdoor applications?

A: No, PEX pipes are not suitable for outdoor use or exposure to direct sunlight as they can degrade when exposed to UV rays.

Q: Are copper pipes more resistant to corrosion than PEX pipes?

A: Yes, copper pipes are highly resistant to corrosion, making them a suitable choice for areas with aggressive water conditions.


In the battle of copper vs PEX pipes, both materials have their own unique set of pros and cons. Copper pipes offer durability, resistance to corrosion, and a long lifespan but come with a higher cost. On the other hand, PEX pipes are flexible, cost-effective, and resistant to freeze breakage but have limitations in terms of UV exposure and high temperatures.

Ultimately, the decision between copper and PEX pipes depends on your specific needs and budget. If longevity and corrosion resistance are top priorities, copper pipes may be the better choice. However, if flexibility and cost savings are more important, PEX pipes could be the way to go. Consider consulting with a professional plumber to assess your specific requirements and make an informed decision.

In the end, whether you choose copper or PEX pipes, what matters most is ensuring a reliable and efficient plumbing system that meets your needs and provides peace of mind for years to come.
