What is the problem with PEX plumbing?
PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.
Should I replace copper water lines with PEX?
Coupled with low production and shipping costs, the savings resulting from installing PEX instead of copper pipes can be significant. Better Energy Efficiency – PEX has a lower thermal conductivity rate than copper. As a result, PEX pipes can help keep hot water hotter for longer periods of time.

Does PEX attract rats?
While PEX comes with convincing reasons for choosing it over copper, it also comes with a hidden downside—rodents seem to find the plastic-based tubing irresistible.
Will PEX freeze and burst?
PEX pipes, just like any pipe, can freeze when the temperature drops too low. Because the pipes are designed to be flexible, PEX has the ability to expand. Although it is still possible for them to burst, this means PEX pipes are less likely to rupture after freezing.
Should I redo my plumbing with PEX?
If just a pipe or a section of your copper plumbing system is leaking, you could just replace it with PEX piping. But if you have an old copper plumbing system that leaks frequently in different areas of your home, you may want to consider a whole-house repipe.

What is better to use copper or PEX?
Copper Pipe Lifespan. PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.
Is PEX or copper better for drinking water?
PEX Advantages Durable and flexible. Less expensive than copper by 25%. Resistant to corrosive water e.g. high acidity “city” water, or mineral heavy water, and electrolysis. Resistant to freeze-breakage.
What is healthier PEX or copper?
The chemical leaching in PEX will go down over time while copper will continue to leach. Personally, many of my own health problems were caused by copper pipes so I’m not a big fan. I would choose PEX over copper every time.
How do I stop mice from eating my PEX?
Mice and rats can squeeze through unbelievably small gaps to enter a home, so the first step is to inspect the home’s outside perimeter and seal all holes and gaps around vent pipes with a rodent-proof sealant, such as Tomcat Rodent Block (available from Amazon).
Do mice chew through PEX pipe?
PEX Pipe Is Vulnerable Rodents Chewing Through PEX Pipe is a common problem in our area. It doesn’t matter how old your home is, if you have an attic, you need to watch for rodent damage to PEX Pipe or PVC.
Do you lose water pressure going from copper to PEX?
You do not lose pressure or volume flow rate by using the larger ID.
Is PEX water line better than copper?
