Why do PEX fittings fail?

Common Causes of PEX Pipe Failures 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.

Do mice eat PEX?

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.
