Posted by Brian Shoemaker

When it comes to selecting the ideal pipe material for your home’s plumbing system, the decision can be quite overwhelming. After all, your choice will impact the functionality, longevity, and overall efficiency of your plumbing system. In this comprehensive guide, we at Advanced Plumbing Technology will delve into the two most popular pipe materials – Pex and Copper – to help you make an informed decision that suits your needs and preferences.

Pex Pipes: The Modern Marvel

Pex pipes, short for cross-linked polyethylene pipes, have revolutionized the plumbing industry with their exceptional versatility and durability. These pipes are created through a unique chemical process that links individual polyethylene molecules, resulting in a robust and flexible piping solution. Here are some key advantages of opting for Pex pipes:

Flexibility and Ease of Installation

Pex pipes are incredibly flexible, making installation a breeze even in tight and confined spaces. Their flexibility eliminates the need for numerous fittings and connectors, reducing the chances of potential leaks. Moreover, Pex pipes can be bent around corners without the need for elaborate maneuvers, reducing the risk of joint failures.

Corrosion Resistance

Unlike traditional metal pipes, Pex pipes are highly resistant to corrosion. This property ensures that your plumbing system maintains its efficiency over time without succumbing to rust or mineral buildup. As a result, Pex pipes are an excellent choice for areas with hard water, where mineral deposits can be particularly problematic.

Durability and Longevity

Pex pipes are designed to last for decades. They can endure extreme temperatures, making them suitable for both hot and cold water applications. The cross-linked molecular structure enhances their resistance to cracks and breaks, further extending their lifespan.

Freeze Resistance

One remarkable feature of Pex pipes is their ability to expand slightly under freezing conditions, minimizing the risk of bursting. This characteristic adds an extra layer of protection to your plumbing system, particularly in regions where frigid temperatures are common.

Copper Pipes: The Time-Tested Classic

Copper pipes have long been the gold standard in plumbing, known for their durability and reliability. These pipes have been used for generations, and they continue to be a popular choice for various reasons:

Proven Track Record

Copper pipes have stood the test of time, with a proven track record of reliability and longevity. Many old homes still boast functional copper plumbing systems, a testament to the material’s enduring quality.

High Heat Tolerance

Copper pipes excel in handling high temperatures, making them ideal for hot water distribution. They can withstand heat without deteriorating or affecting the water’s quality, a crucial factor for many households.

Rigidity and Stability

Copper pipes are rigid and sturdy, which can be advantageous in certain applications. They are less prone to expansion and contraction due to temperature changes, which can be a concern with more flexible materials like Pex.

Biocidal Properties

Copper has natural antimicrobial properties, which means that it can inhibit the growth of bacteria and other harmful microorganisms within the plumbing system. This aspect contributes to maintaining cleaner water quality.

Choosing the Right Pipe Material: Factors to Consider

The decision between Pex and Copper ultimately depends on several factors that are specific to your home and needs. Let’s explore these factors in detail:

Budget Considerations

Pex pipes generally tend to be more cost-effective than copper pipes. If you’re working within a tight budget, Pex might be the more reasonable choice. However, keep in mind that the initial cost should be balanced with the long-term durability of the pipes.

Water Quality

If you live in an area with aggressive water that is prone to corroding metals, Pex pipes might be a wiser option. Copper pipes, while resistant to corrosion, can still be affected by highly acidic or alkaline water.


Consider the specific application of the pipes. For example, if you’re replacing a single section of your plumbing system, matching the existing material might be practical. Additionally, Pex’s flexibility makes it an excellent choice for retrofitting or installations in tight spaces.

Environmental Concerns

Pex pipes have a relatively lower environmental impact during production compared to the energy-intensive process of mining and refining copper. If sustainability is a priority, this could influence your decision.

Local Building Codes

Check with local building codes and regulations, as they might influence your choice of pipe material. Some regions have specific requirements for plumbing systems that you need to adhere to.


In the battle between Pex and Copper, there is no clear winner – it all comes down to your individual needs and priorities. Pex pipes offer remarkable flexibility, freeze resistance, and corrosion resistance, making them a modern marvel. On the other hand, copper pipes boast a proven track record, high heat tolerance, and natural antimicrobial properties, showcasing their timeless reliability.

Before making a decision, carefully assess your budget, water quality, application, environmental concerns, and local building codes. If you’re still unsure, consulting with a professional plumber can provide invaluable insights tailored to your specific situation.
