PEX vs Copper pipes in Vancouver WA - RJ Plumbing ServicesYour home’s water source is a crucial element, whether you’re constructing a new property or considering a repiping project. When it comes to choosing the right materials, two options stand out: PEX and copper. At RJ Plumbing Services, our go-to choice is PEX, and here’s why it’s a game-changer.

The Main Difference Between PEX and Copper Piping

PEX is a flexible plastic pipe capable of running for long stretches with few connections. Since it is flexible and cheap, PEX has quickly gained popularity as a replacement for copper in residential and commercial use. While installation and flexibility are some of the best traits offered by PEX, copper pipes are tried-and-true with decades of durability and the ability to withstand outdoor use and high temperatures.


In the world of plumbing, installation can make or break a project. PEX, a flexible plastic pipe, emerges as the star player. It effortlessly covers long stretches with minimal connections, making installation a breeze. Unlike copper, which demands specialized tools and meticulous soldering, PEX requires fewer fittings, resulting in a quicker, more straightforward setup.


Opting for PEX isn’t just about installation ease – it’s a budget-friendly choice. The streamlined installation process and reduced material requirements translate to significant cost savings compared to copper. Choosing PEX for an average 1,500-square-foot home can lead to substantial savings, making it an economical plumbing solution.


While copper boasts a lifespan of over 50 years, PEX holds its own with a reliable performance range of 25 to 40 years. PEX pipes resist corrosion and scale build-up and demonstrate excellent tolerance to temperature fluctuations. With proper maintenance, PEX delivers lasting performance with less upkeep over the years.


PEX’s flexibility is a game-changer in freezing conditions. It can withstand frosty temperatures without the risk of bursting, a significant advantage over copper. However, it’s crucial to note that PEX may not be the best choice for excessively high temperatures or outdoor usage, where copper traditionally excels.

Water Quality

A crucial consideration is water quality, and PEX delivers here as well. Unlike copper, which may raise concerns about chemicals leaching into the water, PEX is resistant to such issues. With synthetic and plastic materials, PEX minimizes the risk of contaminants infiltrating the water line. Additionally, PEX pipes do not corrode, providing cleaner water without the worry of harmful substances entering your plumbing system.

Environmental Sustainability

Environmental consciousness is a growing concern, and PEX answers the call. With lower energy consumption during manufacturing and a reduced leak potential, PEX stands out as an eco-friendly option. While copper has its merits, PEX takes the lead in addressing sustainability concerns, even if it’s not recyclable.
