When it comes to modern plumbing, PEX pipe has become one of the most popular materials used in home repiping and new construction projects. But what exactly is PEX, and why has it gained such widespread use? In this blog, we’ll take a deep dive into what PEX pipe is, how it works, its advantages over traditional plumbing materials, and why you might want to consider it for your home.

What Is PEX Pipe?

PEX, or cross-linked polyethylene, is a flexible plastic piping material used for water supply lines and radiant heating systems. It was introduced in Europe in the 1960s and has been used in the United States since the 1980s. Over the past few decades, PEX has gained popularity due to its cost-effectiveness, durability, and ease of installation compared to traditional materials like copper and PVC.

PEX pipe is made by chemically cross-linking polyethylene, which gives it flexibility and strength. It’s available in three main types:

1. PEX-A: The most flexible and durable type, often preferred for home repiping and new construction. It is also the easiest to install, particularly for retrofitting older homes.

2. PEX-B: Slightly less flexible than PEX-A but still widely used in residential plumbing due to its affordability.

3. PEX-C: The least flexible and durable of the three, primarily used in less critical plumbing applications.

At We Do Repipes Inc., we always use the highest quality Uponor PEX-A material for residential repipes.

How Is PEX Used in Plumbing?

PEX is commonly used for hot and cold water supply lines. Its flexibility allows it to snake through walls and around corners without many fittings, minimizing potential leak points. PEX is also used in radiant floor heating systems, where it’s embedded in floors to provide even heat distribution throughout a room.

The key advantage of PEX is its adaptability. Unlike rigid materials like copper or PVC, PEX can expand slightly when water freezes, reducing the risk of pipe bursts. Its flexibility also allows for faster and less invasive installations, especially when retrofitting older homes with new plumbing.

The Advantages of PEX Pipe

Here’s why more homeowners and plumbers are choosing PEX for their plumbing systems:

Cost-Effective

PEX is more affordable than traditional copper piping, both in material costs and labor. Since it’s easier to install, plumbers can complete the job more quickly, reducing labor charges.

Easy Installation

PEX’s flexibility allows it to bend around obstacles, meaning fewer cuts in walls and fewer fittings are needed. This makes it ideal for retrofitting older homes, as plumbers don’t have to do as much damage to the walls and floors to install it.

Freeze-Resistant

Unlike copper or PVC pipes, PEX can expand slightly when exposed to freezing temperatures. This makes it far less likely to burst during winter, providing peace of mind in colder climates.

Quiet Water Flow

PEX absorbs sound, meaning you won’t hear the loud banging (water hammer) that is common with metal pipes. This can make for a quieter home, especially when the water is turned on or off quickly.

Corrosion-Resistant

PEX does not corrode or develop scale buildup over time like metal pipes. This leads to a longer lifespan and fewer maintenance issues.

Less Leaking Risk

Since PEX has fewer fittings and joints compared to copper or PVC systems, there are fewer opportunities for leaks to occur. This reduces the likelihood of costly water damage over time.

Potential Drawbacks of PEX Pipe

While PEX has many advantages, it’s important to understand its limitations:

UV Sensitivity

PEX cannot be exposed to direct sunlight for extended periods, as UV rays can degrade the material. This means PEX is not suitable for outdoor plumbing or exposed applications.

Rodent Vulnerability

In some cases, rodents have been known to chew through PEX pipes. If you live in an area with a high rodent population, you may need to take extra precautions during installation.

Chlorine Sensitivity

PEX pipes may degrade more quickly in areas with high chlorine levels. However, modern PEX materials are designed to be more resistant to chlorine than earlier versions.

Professional Installation Required

While PEX is easier to install than rigid pipes, it still requires proper tools and expertise. Connections need to be crimped or expanded carefully to ensure a leak-proof system.

Is PEX Safe for Drinking Water?

One of the most frequently asked questions about PEX is whether it’s safe for drinking water. The answer is yes. PEX piping is certified by several health and safety organizations, including the NSF/ANSI Standard 61, which certifies products for potable water systems.

PEX does not introduce harmful chemicals into drinking water, and it’s resistant to scaling and corrosion that can lead to contamination in other piping materials. In fact, PEX has been rigorously tested and approved for use in water systems for decades, making it a safe and reliable option for your home.

How Long Does PEX Pipe Last?

PEX pipes can last 50 years or more when properly installed and maintained. This longevity makes it an excellent choice for homeowners looking for a durable, long-term solution for their plumbing needs. PEX’s flexibility and resistance to corrosion also mean it is less prone to the common issues that plague metal pipes, such as rust or leaks.

Why Should You Consider a PEX Repipe?

If your home is experiencing frequent leaks, low water pressure, or corroded pipes, it might be time to consider a repipe. Here’s why PEX is a great choice:

• Cost Savings: Lower material and labor costs make PEX a more affordable option than copper or PVC.

• Durability: PEX is highly durable, with a lifespan of over 50 years.

• Quicker Installation: Less invasive and faster to install, meaning minimal disruption to your home during a repipe.
