PEX Plumbing Disadvantages PEX may leach BPA and other toxic chemicals. PEX is extremely sensitive to UV light. PEX can be damaged by chemicals and pests. PEX can’t be installed in high heat areas. PEX is semi-permeable, which means liquid can enter the pipe.
How long does PEX last for?
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
Where is PEX not allowed?
Pex not being allowed in commercial or industrial buildings, and thus not in residential buildings deemed “commercial industrial”.
Why is PEX plumbing bad?
PEX plumbing system has been used for more years and therefore its failures has been observed and known. Its major failures is linked to piping and fitting. Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation.

Pros: Fast and easy to learn, quick to install, relatively inexpensive, tools and products readily available at a variety of retailers. Cons: Crimping works against the “shape memory” of PEX, which always wants to return to its natural shape.

California banned PEX because of the possibility that harmful chemicals can enter drinking water. There are no studies that indicate that you will risk your health if you drink water from PEX pipes.

What is the safest pipe for drinking water?
Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won’t leach chemicals into your drinking water. However, copper pipes are generally more expensive, and copper’s intensive extraction and manufacturing process presents some environmental trade-offs.
Should I replace copper with PEX?
While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems. Keep hot water hot: PEX keeps the water warmer as it flows through the pipe so that you get hotter water on the other end.
Which PEX is best for drinking water?

Is PEX plumbing good or bad?
While PEX is generally considered a safe product and accepted by building codes, the materials and components that comprise the system have several vulnerabilities, and several defective fittings and systems produced by various manufacturers have resulted in leaks and system failures. Sep 26, 2018.
Is PEX worse than copper?
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.
Why is PEX better than CPVC?
CPVC Pipes Offer Better Water Pressure Than PEX With PEX, the pipe fits around the outside of the fitting so the internal diameter of the pipe is reduced at each fitting—even when “full flow” expansion fittings are used. Depending on the fitting used, this can reduce the internal diameter of a ½” pipe by 21% to 35%.
Is CPVC banned in California?
The new regulations approve CPVC pipe for use in residential water supply piping systems. CPVC has been a nationally accepted material since 1982, but California has only permitted its use on a limited basis since 2001.

Does PEX have BPA?
PEX is a form HDPE (high density polyethelene) also know as cross linked polyethylene tubing. The use of BPA in plastics has come under fire for its adverse health affects and although PEX does not contain BPA it contains a number of other chemicals.
Is PEX better than PVC?
PEX pipe is better to use as an electrical and radiant heat insulator in extreme conditions because it resists both better than PVC and CPVC, though PVC is used in combination with a plasticization process to insulate wires.
