I just ran new plumbing for my bathroom using tye M copper 3/4 and 1/2.
A plumber just told we type M is not code for my area and I should have used type L. He also said not to freak out because type M is ok.
After research I see that M is code for NY but not in my town. Also pressure rating is 700psi for 200 degrees as copared to 1000psi for type L.
Does it really matter for a residential system operating at 80psi?
