PEX is also safer to install since a torch is not needed to make connections.

What’s better CPVC or PEX?

If you’re going to be installing pipe indoors and bending it around corners, PEX pipe might be your best choice.

100 yearsAdditionally, 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.

Which is better PEX A or B?

Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.
