You'll Be Glad You Called Us First!
Copper vs. Pex Piping, Which Is Going To Be Best For Your Project?
Choosing between copper and PEX (cross-linked polyethylene) pipes for plumbing comes down to specific needs, budget, and long-term goals. Copper, known for its durability and reliability, has been a standard in plumbing for decades. We offer some insight into both materials here and are ready to help you make a quality decision on which materials to use for your next piping task.
We include great service guarantees on all our work as well.
What is Pex Piping and Why is it Good?
PEX piping, short for cross-linked polyethylene, is a flexible plastic tubing that has revolutionized residential plumbing. Here’s why it’s gaining popularity:
Flexibility and Durability:
PEX is highly flexible, making it easy to work with during installations.
Unlike rigid copper pipes, PEX won’t crack or burst when exposed to freezing temperatures.
Its chemical structure ensures durability, resisting cracks and high temperatures.
Ease of Installation:
DIY enthusiasts rejoice! PEX allows homeowners to replace old copper or galvanized steel pipes themselves.
The colorful tubing (often blue or red) simplifies identification: red PEX carries hot water, while blue PEX carries cold water.
Whether for small repairs or entire water supply systems, PEX comes in various lengths, from short pieces to rolls over 500 feet. Quiet Flow and Safety:
Water flows through PEX pipes quietly, minimizing noise disruptions.
PEX is approved for carrying drinking water, meeting potable water standards.
Antioxidants added during manufacturing ensure its suitability for residential use.
In summary, PEX combines flexibility, affordability, and ease of installation, making it an excellent choice for modern plumbing systems.
How About Using Copper Pipes? How Long Should My Copper Pipes Last?
Copper pipes have been a staple in residential plumbing for decades. Their durability, corrosion resistance, and versatility make them a popular choice. But how long can you expect your copper pipes to last? Let’s break it down:
1. Types of Copper Pipes:
M-Type: These are the thinnest copper pipes, commonly used for residential plumbing. Officially, their lifespan is around 50 years, but reality often paints a different picture. M-Type pipes, exposed to acidic water, tend to corrode faster. As they are thin, they are prone to tearing and developing pinhole leaks. In practice, M-Type pipes may not last more than 20 years.
L-Type: Thicker and more expensive, L-Type copper pipes offer better durability. Their official lifespan is also around 50 years, but many L-Type pipes exceed this. Some have been known to last over 100 years! Investing in L-Type pipes ensures peace of mind, even if your water is acidic.
K-Type: These robust pipes can last 100 years or more. Their longevity makes them a reliable choice for plumbing systems.
2. Factors Influencing Lifespan:
Water Quality: Acidic water accelerates copper corrosion. If your water has low pH levels, M-Type pipes may suffer. L-Type and K-Type pipes handle water quality better.
Wear and Tear: M-Type pipes, being thinner, are more susceptible to wear and tear. Accumulated damage over time leads to cracks and leaks.
Climate and Exposure: Extreme temperatures and corrosive substances impact copper pipes. Proper insulation and protection matter.
Maintenance: Regular inspections and addressing issues promptly extend copper pipe life.
3. Practical Tips:
Replace When Needed: Keep an eye out for pinhole leaks or signs of aging. If your pipes are nearing their lifespan, consider replacement.
Consider L-Type: If budget allows, opt for L-Type pipes. Their longevity justifies the investment.

So Which Should I Use For My RePipe, Copper or Pex?

Copper is generally more expensive both in material costs and installation, requiring soldering and more labor-intensive work. It can also be susceptible to freezing temperatures and may impart a metallic taste to water.
PEX pipes, on the other hand, are flexible, easier to install, and less expensive than copper. They offer a reduction in water hammer noise and are resistant to scale and chlorine damage. PEX's flexibility allows for fewer fittings and a more straightforward installation process, potentially saving on labor costs. However, it cannot be used outdoors due to UV sensitivity and has a shorter track record compared to copper.
Ultimately, the choice between copper and PEX should be based on the specific conditions of the installation, budget considerations, and personal preferences regarding longevity and ease of installation.
