Pros of PEX Pipes For Your Home
Did you know that over 60 percent of newly constructed homes have PEX pipes installed for water supply systems? This is because of various factors that give PEX piping its overall stellar reputation. Plumbing companies, contractors, and homeowners have sought PEX piping for the following reasons.
PEX Piping is Cost-Effective:
This plastic pipe is easier to install and is one of the lightest options when compared to copper pipes. Its low installation cost means you will pay less for PEX and have high-quality piping in your home. Plastic pipes are also cheaper than copper pipes to produce, so those savings are passed down to the homeowner.
Ease of Installation:
Thanks to its physical and usage flexibility, plumbers can use one single-length pipe to connect water lines in hard-to-reach places. PEX connections are easier to install since the fittings require less specialized tools to connect. PEX pipes are easy to install because of their unique color-coding system not available on other pipes. Blue pipes are for cold water, red for hot, and white/gray colored pipes are for both.
PEX Pipes Reduce Noise:
You may hear water flowing through pipes because of loose pipes or high water pressure, but that's not the case with PEX plastic. These pipes provide silent water flow, so you don't hear running water while trying to enjoy music or watch a movie in your living room.
PEX Plastic is Durable:
PEX pipes will not corrode over time like metal pipes. These pipes have a lifespan of 30 years with proper water treatment and a yearly check-up from a professional plumber. PEX piping is also resistant to freeze-cracking, so it can handle temperatures of -40 degrees Fahrenheit without breaking, thanks to its ability to expand and contract.
PEX Pipes Are Energy Efficient:
PEX plastic is an excellent thermal insulator for hot water. With PEX piping, water heater systems use less energy. This ensures that hot water from your home's water heater arrives at your faucets without losing a lot of heat. With thick PEX piping, hot water will lose only one or two degrees of heat which aren’t enough to call it cold water.
Homes provide shelter and protection from outside elements. It's only fair that you use the best available materials for your home so it can continue to serve you and your family. With PEX piping, your family can depend on a good water supply system throughout your house.
PEX pipe is just one of the different pipe materials available for water supply plumbing. Copper is another choice and pipe material worth comparing with PEX plastic.
Cons of PEX Pipes in Your Home
PEX piping sounds like a fantastic option for water supply plumbing in every home, but it does have some drawbacks. Although it has many advantages, you should consider the following PEX pipes' disadvantages in deciding whether this material is a good fit for your home.
PEX Plastic Is Weak to Fire:
The chances of a fire inside your home are very low, but it still remains a nightmare scenario for any homeowner because you can lose everything in your home. But if there were a fire, PEX plastic pipes would melt, requiring new replacement pipes.
Ultra Violet UV Light Sensitivity:
PEX pipes don't do well for outside plumbing, even if underground, because UV light can penetrate through the dirt and affect PEX pipes. If left outside, PEX pipes will deteriorate and become useless. These plastic pipes should not be stored exposed to the sun.
PEX Pipes Are Not Recyclable:
If you are trying to implement an eco-conscious lifestyle, you will not want PEX pipes in your home. PEX plastic can't be broken down like other plastics, like PVC plastic, for reuse. Discarded PEX can end up in landfills instead of being processed for reuse. This plastic can last 30 years, so it isn’t like it’s disposed of every couple of years.
Susceptible to Rodents:
If your home has a rodent problem, it can affect your PEX pipes. On rare occasions, rodents have been shown to chew through PEX plastic. PEX pipes are very thick, but they are still susceptible to rodent damage that can cause pipes to crack or break.
Possible Leaching:
Although uncommon, some homeowners and plumbing companies have reported a few PEX pipes leaching harmful contaminants like BPA (Bisphenol A) into the water supply. BPA chemicals can cause neurological, reproductive, and immunity issues, according to scientific study
Brief History of PEX Pipes in Plumbing
Unlike copper, which dates back to ancient times, PEX plastic was created in 1968 by German scientist Thomas Engle. The material was used in Europe for water supply plumbing but wasn't used as frequently in the United States until 30 years ago.
PEX piping is a lot more common today and is available in three different types:
PEX-A:
This pipe provides the most flexibility and is suitable for all water supply plumbing needs. It is also the most resistant to freeze cracking. PEX-A pipes are manufactured using peroxide.
PEX-B:
PEX-B pipes are great for pools since it has increased chlorine resistance. These pipes also have great coil memory, returning to their original shape when it expands.
PEX-C:
PEX-C plastic pipes are the lowest in price compared to the other two, but they may crack in freezing temperatures. It's also the least flexible, so it is not commonly used.
Most homeowners don't have to worry about choosing which type of PEX plastic pipe to install. Experienced plumbers will always select the best materials to do the job efficiently.

Polymers, plastic, and all kinds of synthetic material are replacing the good old days of metals when it comes to housing and construction. One of these popular furnishings is PEX plumbing pipes. PEX pipes became popular in the ‘80s and ‘90s and thousands of houses today still have them. While they were all the rage when they first came out, over the years, many of its shortcomings have come to light.
If you’re considering PEX plumbing in your house, you might want to reconsider. Here’s why:
What is PEX Plumbing?
According to The Balance Small Business, PEX is a cross-linked polyethylene in a tube form for plumbing purposes. The high prices of copper led many people to opt for PEX plumbing. PEX material is also favored for its flexibility when it comes to fitting. PEX can be bent around to accommodate a good fitting and is preferred over copper and polyvinyl chloride piping. Undoubtedly, PEX pipes are one of the easiest pipes to install. However, they come with quite a few downsides and could end up costing house owners thousands of dollars in damage.
Let’s discuss in details: why PEX plumbing is bad for your house:
Why is PEX Plumbing Bad for Your House:
1. Chlorine
PEX plumbing and chlorine do not mix well, which is ironic. Chlorination badly affects the durability of the PEX plumbing system and shortens its lifespan. The chlorine in the water inside PEX pipes speed-up the brittle oxidative failure of cross-linked polyethylene. This failure leads to sudden leakage and sometimes even bursting of the pipes.
To combat this failure, manufacturers began to add antioxidants into the PEX piping. However, it only ended up delaying the oxidation to a slight degree. Now, the chlorine degrades the antioxidants first but eventually ends up reaching the pipe and causing failure.
2. Light
PEX plumbing lacks versatility because of its sensitivity to light. PEX cannot be taken anywhere outside the house where it is directly exposed to UV for a long period. The synthetic material of the pipes can slowly disintegrate due to the light of the sun. Even light bulbs have been known to affect the lifespan of PEX water lines.
3. Bacteria
While this is a rare failure, it still happens. Under unique circumstances, PEX water lines become highly susceptible to bacteria. This mostly happens when PEX pipes are installed deep under the ground and vulnerable to moisture. In extreme cases, the bacteria caused by moisture can penetrate inside the PEX pipes and contaminate the water.
4. Non-Recyclable
As is the case with most plastics, PEX pipes are also non-recyclable. Large pieces of PEX pipes are discarded when new water lines are installed. Unfortunately, we have yet to find a way to bring these discarded pipes back to use. Until then, all that plastic has nowhere to go.
5. Rodents
A very common problem reported by many users is that PEX pipes are vulnerable to rodent attacks. Unlike copper pipes, rodents’ sharp teeth can easily chew through PEX water lines. This damages the entire waterline and eventually leads to leakage and contamination. If your house has a particular rodent problem then have your water lines checked and opt for a material that is resistant to rodent attacks.
6. Quality of Water
One of the biggest downsides of PEX plumbing is that some of them affect the taste and odor of water. It’s important to know about this risk before installing PEX water lines in your house. In some cases, the smell and taste are so unpleasant, that people have to replace the pipes all over again. Due to a lack of research on the subject, the reasons behind the unpleasant taste and smell are unknown.
Better Options than PEX
The following options might be costlier than the plastic plumbing, but they’d last a long time and give you the ultimate peace of mind. Here you go:
- Copper: Copper pipes are tough. They are heat resistant, safe from corrosion, and are naturally antimicrobial.
- Polyvinyl Chloride Piping (PVC): PVC pipes are an inexpensive alternative to copper pipes. They are resistant to rust and corrosion and can sustain high-pressure water.
