Why is Pex Plumbing Bad For Your Home?
Have you ever wondered why some people are unsure about using PEX plumbing in their homes? While PEX (cross-linked polyethylene) plumbing is popular because it is flexible and easy to install, there are some important reasons to think about before choosing it.
PEX plumbing is considered bad because it can leak harmful chemicals, doesn’t last as long as other materials, and can get damaged by sunlight. Knowing these issues can help you make better choices about your plumbing system.
In this article, I will show you why Pex Plumbing is bad for you. We will also discuss the Cost of Pex Plumbing and its Lawsuits.
9 Reasons Why is Pex Plumbing Bad For You
Here are the main reasons why is PEX plumbing bad.
1. Leaking Harmful Chemical
One of the main reasons why is PEX plumbing bad is that PEX pipes can release harmful chemicals into your drinking water, especially when they are new.
Some studies have shown that certain types of PEX may leak substances like bisphenol A (BPA), which can be bad for health.
These chemicals may cause problems like hormonal issues and other health risks. Even though the amounts might be small, their long-term effects are still a concern for many people.
2. Sensitivity to Chlorine
Another reason why is PEX plumbing bad relates to its sensitivity to chlorine, which is often used in city water supplies to kill germs.
High levels of chlorine can break down PEX pipes, causing them to become brittle and leading to cracks or leaks. This can result in expensive repairs and water damage. Homeowners in areas with a lot of chlorine in their water should think carefully before choosing PEX.
3. UV Light Damages
A significant issue contributing to why is PEX plumbing bad is its susceptibility to damage from sunlight (UV light). Prolonged exposure to sunlight can cause PEX pipes to deteriorate, rendering them ineffective for outdoor use.
Even if they are buried underground, UV rays can still affect them over time.
This limitation necessitates careful installation and protection from sunlight, which can complicate outdoor plumbing projects.
4. Not Good in Extreme Temperatures
PEX pipes do not work well in very hot or very cold temperatures, which is another reason why is PEX plumbing bad. In hot places, like near water heaters, PEX can warp or get damaged.
In freezing weather, PEX pipes might crack if they are not insulated properly. This makes them less reliable in areas with extreme temperature changes.
5. Easily Damaged by Rodents
Since PEX is made from plastic, it is more vulnerable to damage from rodents like rats and mice. These animals can chew through PEX pipes, causing leaks and possibly contaminating the water supply.
This risk adds to the list of reasons why is PEX plumbing bad for homeowners who have rodent problems.
6. Can’t Be Recycled
Unlike copper pipes that can be recycled when they are no longer needed, PEX cannot be recycled. This characteristic raises environmental concerns because discarded plastic pipes end up in landfills and contribute to plastic waste.
For those who care about the environment, this aspect of why is PEX plumbing bad may be significant.
7. Installation Issues
Although PEX is generally easier to install than traditional materials like copper, mistakes during installation can lead to various problems.
If connections are not made correctly or if the system fails a pressure test, leaks can happen. Some types of PEX also require specific fittings that can complicate repairs or replacements down the line.
8. Possible Bad Taste or Smell
Many people have noticed bad tastes and smells in their water after installing PEX plumbing systems. These issues often come from chemical leaching or bacteria growing inside the pipes.
If these problems occur, homeowners may need to flush their systems thoroughly or even replace parts of their plumbing, further supporting why is PEX plumbing bad.
9. Not Fire Resistant
Although it is rare, there is a risk related to fires and PEX plumbing that contributes to why is PEX plumbing bad overall. If there is a fire, PEX pipes can melt and lose their strength, which could lead to more damage during firefighting efforts.
While fires are not common in most homes, it’s still something to consider.

Cost of Pex Plumbing
The cost of PEX plumbing can vary significantly based on several factors, including the size of the home, the number of fixtures, and local labor rates.
Cost of PEX Pipes
| Cost Category | Details | Estimated Cost |
|---|---|---|
| Material Cost | PEX pipes per linear foot | $0.40 – $2.50 |
| Installation Costs | Total cost for installing PEX plumbing | $1,500 – $15,000 |
Average Cost Estimates
| Home Size | Estimated Cost |
|---|---|
| Small home (1 bathroom) | $1,500 – $2,500 |
| Medium-sized home (2.5 baths) | $3,000 – $7,000 |
| New construction using PEX | $5,000 – $21,000 |
Environmental Impact of Using Pex Plumbing
The environmental impact of using PEX plumbing goes beyond its inability to be recycled:
- Plastic Waste: The production and disposal of plastic materials add significantly to global plastic waste problems. As more homes use PEX plumbing systems, the number of discarded pipes increases.
- Chemical Pollution: Chemicals leaking from new PEX pipes into local water supplies raise concerns about contamination over time.
PEX Pipe Insurance Problems
Homeowners should also know about potential insurance issues related to using PEX plumbing. Some insurance companies see PEX as a higher risk because it can leak or get damaged from rodents or UV exposure.
This means homeowners might have higher insurance premiums or find it harder to get coverage for homes with a lot of PEX plumbing.
PEX Piping Lawsuit
There have been cases where homeowners sued manufacturers of PEX piping due to problems like early failure or chemical leaching. These lawsuits often claim that manufacturers did not properly inform consumers about the risks associated with their products, resulting in financial losses for homeowners.
Where is PEX Not Allowed?
1. New York City
- Ban on PEX: PEX is prohibited due to concerns about:
- Chemical Leaching: Potential health risks from chemicals leaching into drinking water.
- Fire Safety: PEX is made of plastic, raising fire safety concerns in densely populated areas.
- Durability: Questions about its long-term durability compared to traditional materials like copper.
2. Specific Building Codes
- International Residential Code (IRC): Restrictions include:
- Not allowed for piping under floor slabs or buried pipes unless permitted.
- Restrictions on connections to water heaters within the first 18 inches.
- Uniform Plumbing Code (UPC): Requires third-party certification and proper support for PEX installations.
3. Other Local Regulations
- Some municipalities may restrict PEX due to:
- Lack of Familiarity: Local plumbers may be less experienced with PEX.
- Concerns About Plastic Pipes: Past issues with other plastic piping systems lead to caution.

Other Options Instead of Pex Plumbing
1. Copper Pipes
- Durability: Copper pipes are very strong and can last over 50 years.
- Resistance: They resist corrosion and can handle high temperatures and pressures.
- Versatility: Suitable for both hot and cold water lines, as well as gas lines.
- Installation: Requires soldering or special fittings, which can be more labor-intensive and costly than PEX.
2. PVC Pipes
- Lightweight and Easy to Use: PVC (polyvinyl chloride) pipes are lightweight and simple to install, making them a popular choice for drain, waste, and vent lines.
- Cost-Effective: Generally cheaper than both PEX and copper pipes.
- Durability: Resistant to rust and corrosion, but not suitable for high-temperature applications.
- Limitations: Cannot be used for hot water supply lines and may become brittle over time if exposed to UV light.
3. ABS Pipes
- Strong and Lightweight: ABS (acrylonitrile butadiene styrene) pipes are known for their strength and flexibility.
- Easy Installation: Like PVC, they are easy to cut and fit together with solvent cement.
- Applications: Commonly used for drain lines and waste systems.
- Temperature Sensitivity: Not as resistant to heat as copper or PEX, so they are not suitable for hot water lines.
