Why is PEX Plumbing Bad? Understanding the Pros, Cons, and Myths

When it comes to plumbing, PEX (cross-linked polyethylene) tubing has gained significant popularity due to its affordability, flexibility, and ease of installation. However, despite its widespread use, concerns have been raised regarding its safety and durability. So, is PEX plumbing really bad? In this post, we’ll address these concerns, dispel common myths, and provide you with the information you need to make an informed decision about using PEX in your home.

What is PEX Plumbing?

PEX tubing has been a game-changer in the plumbing industry. Unlike traditional copper piping, PEX is resistant to corrosion, doesn’t require soldering, and can be easily installed in tight spaces due to its flexibility. It’s commonly used for residential water supply lines and is known for its longevity and cost-effectiveness.

Common Concerns About PEX Plumbing

1. Safety Concerns: Is PEX Tubing Safe for Drinking Water?
   • Myth: Some people believe that PEX tubing is unsafe because it’s made of plastic, which might leach harmful chemicals into the water.
   • Fact: PEX tubing is BPA-free and does not contain other harmful chemicals that could leach into your water supply. Numerous studies, including a comprehensive Norwegian study, have shown that PEX is safe for drinking water and poses no health risks.
2. Taste Issues: Does PEX Affect Water Taste?
   • Myth: Water from PEX pipes may have a strange taste, leading some to believe that the tubing is contaminating their water.
   • Fact: In rare cases, PEX tubing can impart a temporary taste to the water, especially if it’s new or if water has been sitting in the pipes for an extended period. However, this is not a safety issue, and the taste typically dissipates after a few uses or by letting the water run for a minute before consumption.
3. Durability Concerns: Is PEX as Reliable as Copper?
   • Myth: PEX is less durable than copper and more prone to leaks or failures.
   • Fact: PEX is highly resistant to scale, chlorine, and corrosion, which makes it a durable choice for plumbing. While it is more permeable than copper, proper installation and use in suitable environments ensure that PEX can last as long as copper piping, often up to 50 years or more.

Advantages of PEX Plumbing

• Cost-Effective: PEX is significantly cheaper than copper, both in terms of materials and installation labor.
• Flexibility: PEX can bend around corners and run through walls easily, reducing the need for fittings and joints that can leak over time.
• Freeze Resistance: PEX is more resistant to bursting in freezing temperatures due to its flexibility.

When to Consider Alternatives to PEX

While PEX is a great option for many plumbing situations, there are cases where copper or other materials might be more suitable:

• High-Temperature Applications: In areas where extremely high temperatures are common, copper may be a better choice due to its higher heat tolerance.
• Historical Homes: For homes where preserving the original building materials is important, copper may be preferred for aesthetic or structural reasons.

Should You Choose PEX for Your Home?

The decision to use PEX or another material depends on your specific needs, budget, and the environment in which it will be used. However, for most homeowners, PEX offers a reliable, safe, and cost-effective solution for plumbing needs.
