Is it ok with plumbing code to mortar around a copper hose fawcet pipe?

Question

A 1/2 " copper pipe goes through concrete foundation and then stonework to hose bib. Can I mortar right around the pipe inside and outside to seal the hole?

Thanks for your advice

Answer 1

You can caulk around it.  Mortor will shrink.

Answer 2

We sleeve it then caulk it. Concrete leeches lime (a corrosive) forever. It will slowly eat the tubing away.

Answer 3

Concrete reacts with copper. If you decide to run your pipe through concrete, wrap it with insulation, or duct tape to prevent direct contact.
