Can you bury PEX under a slab?

Otherwise it should be sheathed to allow it to comfortably expand depending on temperature variations, it also makes it possible to change the pipe if it bursts due to freezing, or bad quality pipe for example.

How do you install PEX on concrete?

How long will PEX last underground?

PEX has a life expectancy of 40-50 years, made possible by its durable and non-corrosive materials. Burial also reduces sun exposure, which would otherwise degrade the piping. Additionally, PEX tubing materials allow for expansion, making them resistant to freezing/cracking underground.
