As your home ages, so too do its pipes. Years of use can lead to frequent leaks, water pressure issues, rusty or discolored water, and other noticeable signs of deterioration. Even more serious are the unseen problems—unstable plumbing infrastructure can lead to widespread water damage, mold growth, and reduced water quality. If you’ve been battling persistent plumbing issues or live in a several decades-old home, it may be time to consider a full home repipe. Among the variety of materials available, cross-linked polyethylene, or PEX, offers a flexible, durable, and cost-effective solution for modernizing your home’s plumbing system. Recognizing when it’s time to repipe and choosing the benefits of PEX for the job could ensure reliable water delivery for years to come while also increasing the value of your home.
Cross-linked Polyethylene (PEX) for Various Industries?
Cross-linked polyethylene, or PEX, is a type of polyethylene that has undergone a process called cross-linking. This process bonds the polymer chains in the polyethylene together, creating a more durable, flexible, and heat-resistant material than regular polyethylene.
PEX is a popular material in various industries due to its many beneficial properties. For example, commonly used in the construction of water supply lines in residential and commercial plumbing because it’s less likely to burst when the water inside it freezes, and it can withstand high water pressure.

PEX is an Excellent Material for Many Applications
There are several types of PEX: PEX-A (peroxide method), PEX-B (silane method), and PEX-C (electron beam or radiation method), each made through a different cross-linking method and featuring slightly different properties. All types, however, benefit from the general characteristics of PEX: flexibility, resistance to both freezing and heat, chemical resistance, and longevity. Remember that while PEX is an excellent material for many applications, like most materials, it could be better for some things. For instance, it doesn’t perform as well in high-temperature, high-pressure environments or when exposed to sunlight. But it can offer superior performance and cost savings in its recommended applications.
The History of PEX
Cross-linked polyethylene, or PEX, has an interesting history. The development of PEX began in the 1960s in Europe, where the material was first invented. It took a little while for PEX to find widespread use. Still, by the 1980s, it was becoming a popular material for radiant floor heating systems in Europe due to its resistance to heat, flexibility, and durability.
The use of PEX in North American residential homes became common in the 1990s and early 2000s. Initially, PEX was used primarily for underfloor heating, similar to its usage in Europe. However, North American plumbers and builders soon realized the benefits of PEX for other residential plumbing applications as well.
Now Widely Accepted in California and Across The U.S.
Nowadays, installers commonly replace copper or PVC for many hot and cold water plumbing applications in residential construction, from the main water service line to indoor plumbing. The product’s flexibility allows for fewer joints. Additionally, plumbers can easily manipulate the tubing by pulling through walls and around corners, reducing the need for holes and notches at the risk of leaks. Its resistance to scaling and chlorination, and its capacity to withstand freezing temperatures, have also made PEX a popular choice for home plumbing systems.
However, despite these advantages, PEX has also faced some controversy. Although, through industry studies and manufacturing changes, PEX is now widely accepted in California and across the U.S.
Still today, PEX continues to gain popularity and increased recognition for its potential to improve residential plumbing systems’ ease of installation, durability, and cost-effectiveness.
Some of The Pros and Cons of PEX and Copper
PEX and copper are two different types of materials used in plumbing applications. Each material has its advantages and disadvantages, and the choice between the two often depends on the specific needs of the project. Here are some pros and cons when comparing the benefits of PEX to copper:
PEX – Pros:
- Flexibility: PEX piping is flexible, which makes it easier to install than rigid materials like copper. This flexibility allows PEX to bend around corners without needing elbow fittings, making installation faster and simpler.
- Cost: PEX is generally less expensive than copper in terms of material cost and installation labor.
- Durability: PEX is resistant to corrosion and scaling, problems that can afflict copper pipes. It is also resistant to freeze-breakage.
- Noise: PEX absorbs the noise of flowing water better than copper, making it quieter.
- Heat Fusion: PEX connections can be heat-fused, eliminating the need for soldering and making connections potentially more reliable.
PEX – Cons:
- UV Sensitivity: PEX piping is sensitive to UV light and cannot be used in applications where it will be exposed to sunlight.
- Permeability: PEX can be permeable to certain chemicals, potentially impacting the water supply’s quality.
- Appearance: Some homeowners and professionals prefer the traditional look of copper over PEX.
Copper – Pros:
- History: Copper piping has been used for decades and has a proven track record of reliability.
- Heat Resistance: Copper has a higher resistance to heat than PEX, making it suitable for applications with high temperatures.
- Non-Permeable: Copper is impermeable to gases and liquids, protecting the quality of the water supply.
- Appearance: Many homeowners still consider copper more aesthetically pleasing than PEX.
Copper – Cons:
- Cost: Copper is typically more expensive than PEX, both in terms of the material itself and the installation cost.
- Corrosion: Copper pipes can corrode over time, leading to leaks and other problems.
- Rigidity: Unlike PEX, copper is a rigid material requiring more fittings and complex installation.
Ultimately, the decision between PEX and Copper will depend on the project’s specific needs, local building codes, and personal preferences. Each material has its strengths and weaknesses; both are viable options for many plumbing applications.
