Copper repipe on concrete.

Is it ok to run copper pipe on top of concrete as in this photo? If it’s ok to be embedded in concrete why not on top if it is not in a vulnerable location?

Yes it is OK .

Your question is addressed in the IRC (2015) P2603.3. Also when would the placement of any water distribution pipe directly in a walking path and unprotected be proper?

BTW you might want to call the ICC and have them check your certification listing for “Int. Code Council Building Inspector Certification #5214502-10”. The certification odes not appear to be current or they have made an error in updating their system.
