Copper Pipe Vs PEX – Which Is Best For Your Home?

When replacing your pipes, you have the option of copper pipe or PEX. Both materials offer advantages, but you need to determine which option is best suited for your home.

Copper has a long and esteemed piping material. However, PEX is becoming more and more popular due to its lower cost and ease of installation.


When selecting piping for your home, two primary options are copper pipe and pex. Each has its own advantages and drawbacks; therefore, it’s essential to understand the distinctions between them in order to decide which option is best suited to your needs.

Copper pipes are a reliable and long-term choice, but they’re pricey due to the high production costs associated with mining and manufacturing copper.

On the other hand, PEX is an economical and eco-friendly alternative to copper. It uses less energy during production and requires fewer fittings, which could save you money in the long run.

PEX pipes are more flexible than copper pipes, making them less likely to burst when water freezes inside of them. This makes PEX an ideal choice for new homes in cold climates.

Another advantage of PEX is that it won’t corrode like copper can. Furthermore, unlike copper, PEX does not leach toxins into the water supply like it can.

However, it should be noted that PEX tubing is not UV stable and thus not ideal for outdoor installations. Furthermore, the chemical composition and quality of tubing may vary between manufacturers, potentially affecting performance and lifespan of the product.

Copper pipe costs vary based on market and supply chain conditions, though it tends to be more costly than PEX. However, copper may be a better option for certain plumbing systems due to its inherent corrosion resistance.

Copper piping, for instance, is more resistant to acidic water than PEX and more durable against mineral buildup caused by hard water. Furthermore, copper piping has bacteriostatic properties (meaning it inhibits bacteria growth) as well as being corrosion-resistant.

On the contrary, copper piping can be challenging to install due to its need to be soldered and connected with brass fittings. This process takes time and requires basic skills, making the job more complex for homeowners or DIYers.

Finally, it’s up to you to decide which type of piping works best for your requirements and budget. The most efficient way to do so is by consulting a professional plumber. They can inspect your plumbing system and offer recommendations based on the most effective materials suitable for your home.


When selecting materials for plumbing systems, there are plenty of options. Some are better suited to certain tasks than others depending on durability and cost; when selecting the perfect option for your project, take into account factors like durability and budget.

Copper pipe is a robust material that can withstand pressure and rodents alike. Additionally, it’s impermeable and resistant to UV rays, meaning your pipe won’t deteriorate over time.

Corrosion-resistant PVC pipes make them the ideal choice for use with hot water, as well as being less likely to corrode when exposed to acidic water. On the downside, however, PVC may be more expensive than PEX and you may need to hire professionals with soldering skills if your copper pipes require soldering.

For a more budget-conscious option, PEX tubing (made of cross-linked polyethylene) may be your best bet. Not only is this cheaper than copper piping but much easier to install as well.

Another advantage of PEX is that it requires less energy to manufacture, helping you reduce your carbon footprint. Furthermore, it does not rely on extracting finite natural resources like copper does – another major plus for the environment.

Both copper and PEX piping have their advantages, it’s essential to remember that these materials aren’t perfect. Each has its own strengths and drawbacks, making it difficult to decide which is the most suitable option for your project.

Durability is a paramount concern for home builders and homeowners alike. To ensure your piping system remains strong and resilient, it’s essential that you invest in quality components now to save yourself costly repairs in the future.

Copper piping is typically the best material for long-term use due to its resistance to high pressure and extreme heat. Furthermore, its resistance against water damage and rodent infestation makes it ideal in areas prone to floods or other natural disasters.

Water-hardened metals such as stainless steel are more resistant to mineral buildup from hard water, which can restrict flow. Furthermore, high pH environments (especially alkaline water) may corrode this metal so it’s not recommended for homes that experience frequent hard water usage.

Copper is more costly, but it has a longer lifespan and is often preferred by experts. Its durability is especially crucial if you plan to use it in areas that experience freezing weather; otherwise, your copper pipe could freeze and burst, causing extensive water damage in your house.

Environmental Impact

Copper piping has been the standard in many plumbing systems for decades, but PEX is becoming an increasingly popular alternative due to its superior water quality, lower maintenance needs, and long lifespan.

The environmental impact of piping depends on its use, but most experts agree that plastic pipes are more eco-friendly than copper and can significantly reduce CO2 emissions over its lifespan. Furthermore, PEX pipes are much more flexible than copper which helps save on materials and energy in buildings’ plumbing systems.

PEX tubing for water or hydronic systems offers several advantages over other materials, such as reduced waste from bends around corners and improved system efficiency. Furthermore, its flexibility prevents tubing from sagging or cracking which could result in leaks or other property damage.

Another key advantage of a PEX system is its capacity to expand when temperatures drop, so it can accommodate freezing water without breaking or shrinking like copper can. This property makes it an ideal solution for homes that experience pipe bursts due to cold temperatures.

Polyethylene in a plumbing system doesn’t use much energy during production and doesn’t emit any greenhouse gas during its lifespan. It makes for an eco-friendly home, especially if you can incorporate it into closed loop heating applications like radiant floor heating, snow melting and baseboard radiators.

One of the major disadvantages to copper piping is that it requires more energy to heat water than polyethylene does. Copper conducts heat away from its source to the spout or showerhead, so hot water takes longer to reach its destination.

Copper smelting and production also emit environmental emissions which have been known to be toxic to humans and the environment. Furthermore, some individuals may experience flu-like symptoms or other health issues when exposed to copper; it’s still uncertain whether this metal is carcinogenic.


Planning a plumbing project? It is essential to determine which type of piping material best meets your requirements. While this can seem like an intimidating task, making the right selection will guarantee both functional and economical outcomes in the end.

Copper and PEX are the two primary piping materials used for residential plumbing applications. Each has its own advantages and drawbacks, depending on the application.

Copper pipes are a popular choice for homeowners due to their greater resistance to pressure than other pipe materials. Furthermore, copper pipes boast an impressive longevity; most will last 50 years or more with proper care and maintenance. Unfortunately, installing these pipes can prove expensive due to their weight, however.

Copper piping offers several major advantages over its steel counterpart, including being recyclable and eco-friendly while lessening their impact on the environment. Furthermore, copper pipes are resistant to corrosion and do not leach toxins into water sources.

However, copper pipes can break if the water inside them freezes. This poses a major concern for homes located in cold climates since copper may not be able to handle the extreme temperature changes caused by freezing water.

Selecting the ideal piping material can be a complex decision that should be carefully thought through and understood by both homeowners and professional plumbers. When making this choice, consider factors like project location, purpose and budget when making your selection.

For instance, if the plumbing application involves baseboard heating or radiant floor heating, PEX would likely be the better choice due to its versatility and ease of installation.

But for kitchen or bathroom sink piping, copper may be the better option due to its superior chlorine resistance. Furthermore, copper is more flexible and user friendly than PEX.

In some cases, both materials can be combined into a single system. This can be an advantageous choice for many home remodeling projects as it will save you money on multiple materials and installation fees.

Ultimately, the best decision for your project depends on a case-by-case analysis. A professional plumber can give an accurate assessment of which piping system is ideal and suggest the appropriate type of pipe tailored to your unique situation.
