How long will PEX last?
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.
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 Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. Attaching PEX tube to fittings does not require soldering, and so eliminates the health hazards involved with lead-based solder and acid fluxes. PEX is also safer to install since a torch is not needed to make connections.
Can rats eat through PEX pipe?
Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home’s PEX water pipes, the result can be disastrous.
