PEX covering needed in cinder block and furried wall?

[DIY DOC]

I have some PEX pipping coming from the attic, through the cinder block, and out into the bathroom sink. I also have some areas where the PEX is touching the outer surface of the cinder block and dry wall (I have ~ 3/4 maybe 1" of clearance due to thin furried drywall).

Do I need to cover the PEX pipe with any protective sleeve? I'm concerned with rubbing.


Thanks in advance for any recommendation and advice.

I would protect, and always support properly in all directions.
