How to Decide Between PEX and Copper Piping for Your Home

pex vs. copper piping for home

Like most home improvements, pipe replacements are costly. Modern homeowners are opting for more affordable, flexible options such as PEX (Polyethylene) pipes because they don’t require as much initial overhaul as copper pipes. Older homes feature traditional copper piping, as this is what was popular for plumbing from the ’60s on. 

In this guide, we’ll help you determine which kind of piping is the best for your cost, style, and labor preferences. If you need professional assistance picking out your home pipes, don’t hesitate to reach out to Sunny Service. DFW residents can easily reach us via phone or email.

What Is PEX Piping?

Also known as “polyethylene piping,” PEX piping is a modern alternative to copper. Introduced in the 1980s, PEX continues to be an affordable home plumbing option. While it may not retain the same longevity as copper, the plastic material PEX is made of affords homeowners the flexibility to change their minds.

Popular in both residential and commercial properties, PEX piping is:

  • Made from Cross-linked Polyethylene, a flexible plastic material
  • Used in residential and commercial plumbing for water supply lines
  • Lightweight, easy to install, and resistant to freezing
  • Common in modern construction and remodeling projects

What Is Copper Piping?

When people think of their plumbing systems, they often think of those bright, industrial copper pipes. Many people prefer copper pipes to this day, especially those still living in mid-century homes. Below is an overview of what copper pipes are:

  • Metallic piping used in plumbing for decades
  • Durable, naturally resistant to bacteria, and recyclable
  • Found in older homes but still preferred for certain applications
  • Requires soldering for installation, making it more labor-intensive

Pros and Cons of PEX Piping

Other than the age and material differences, there are additional things to consider. Is the initial cost of the pipe installation sustainable for you? Is your home built in a way that would allow a seamless installation?

PEX piping is desirable to a lot of homeowners because it’s easy to install, flexible, and low-cost. It’s additionally a convenient option because no drywall needs to be removed to install it. We ask homeowners to consider these pros and cons before making a decision:

Pros:

  • Flexible and easy to maneuver through walls and tight spaces
  • Cheaper materials and installation costs
  • Resistant to corrosion and scaling
  • Can expand slightly, reducing the risk of bursting from freezing
  • Quiet operation, no water hammer noise

Cons:

  • Can’t be used outdoors due to UV sensitivity
  • Potential chemical leaching concerns in certain water conditions
  • Rodents have been known to chew through PEX pipes

Pros and Cons of Copper Piping

Copper pipes are made out of a time-resistant metal material that doesn’t wear down from age, damage, or weather. 

Although initially costly, the longevity of copper piping ends up being greater than whatever is spent. If the cost, rigidity, and labor required to install copper pipes don’t faze you, these highlights shouldn’t either:

Pros:

  • Extremely durable and can last over 50 years
  • Resistant to bacteria and doesn’t degrade over time
  • Handles high temperatures well and is UV-resistant
  • Can add value to a home due to its longevity and reliability

Cons:

  • More expensive than PEX in both material and labor
  • Prone to corrosion in areas with acidic water
  • More rigid, requiring more fittings and longer installation times
  • Noisy when water pressure fluctuates (water hammer effect)

Cost Comparison: PEX vs. Copper

Now, let’s break down the real price difference between PEX and Copper pipes. It’s not only the number of team members it takes to install each material but also how many tools it takes to do so. 

Because copper pipes have to be cut and shaped, they require a more intensive service. Both copper and PEX pipes are a gamble, as you can’t predict things like corrosion or freezes.

It’s best to stick with the concrete facts and give the rest to the professionals. If you choose one of the two options and end up stuck with costly maintenance, we’ll make it easy to receive help.

Sunny Service recommends considering the following cost differences when choosing a home piping option:

  • Material Costs: PEX is significantly more affordable than copper
  • Labor Costs: PEX is easier and faster to install, reducing labor expenses
  • Long-Term Costs: Copper lasts longer but can corrode; PEX may need replacement due to wear or external damage
  • Repairs & Maintenance: PEX is easier and cheaper to replace, while Copper requires soldering and more effort

Best Applications for Each Type

While you may like the industrial look of a copper pipe, it may not work well in your home. Maybe you’re looking to remodel your home. PEX is a great option for newer homes because it’s easy to manipulate, whereas installing copper piping in a new home would require major reworking.

Look for what will make your life easier, whether it’s the installation process or the level of resistance.

Copper is going to yield the easiest installation process in older, traditionally built homes, as they already have the necessary space.

PEX or copper, our team is available to find the best fit for you. We’ve rounded up the best applications for each pipe type below:

  • PEX is Best For:
    • New construction and remodels
    • Budget-conscious homeowners
    • Areas with freezing temperatures
    • DIY-friendly plumbing projects
  • Copper is Best For:
    • High-temperature applications (hot water, heating systems)
    • Homes where long-term durability is a priority
    • Outdoor plumbing and direct sunlight exposure
    • Increasing home resale value
  • Hybrid Systems:
    • Combining PEX and Copper for different parts of the plumbing system
    • Using Copper for main lines and PEX for interior distribution

Environmental and Health Considerations

While it makes sense to first consider the functionality and durability of each pipe type, it’s equally important to consider the environment and health impact as well. 

The plastic makeup of PEX pipes could be a serious concern for some homeowners, while others may struggle more with the leak potential of copper pipes. Before you make a decision, ask your installation service provider about the manufacturing information.

Environmentally, copper pipes seem to be the better choice. They’re recyclable, durable, and long-lasting. However, they’re not without fault.

Once again, look at the material. The best choice for you will always be the option that aligns with your needs. Contact an expert at Sunny Service if you need assistance weighing your options.

Before we get to you, think about what’s important for your home:

  • Sustainability: Copper is 100% recyclable, whereas PEX has a more complex recycling process
  • Health Concerns:
    • Copper can leach into water in corrosive conditions
    • PEX may have concerns about chemical leaching, depending on the manufacturer
  • Energy Use:
    • Copper production is energy-intensive, while PEX has a lower manufacturing footprint

The Takeaway

Are you planning to stay in your house for a long time? Are you on a budget? These are questions to ask yourself before settling on a material. Luckily, Sunny Service can help you make an informed decision. DFW residents can call, email, or contact us via our website for an immediate consultation. 

Cost, durability, and installation may be important, but not more important than your home comfort.
