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.
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.
Is PEX banned in California 2020?
PEX was banned in California due to some concerns about toxic materials leaking through the pipe and into water. Through various national laboratory tests, PEX has proven to be completely safe and durable. It is now legal in California and even included in principal plumbing codes.
Is PEX plumbing good or bad?

Which is better PEX A or B?
PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. ... 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases. PEX-B is a clear winner in terms of price vs. both other types.
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.

What is the most reliable PEX connection?
PEX-A , which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant.
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 1⁄2” pipe by 21% to 35%.
