Good chance the original work was done with a bad batch of pipe, or worse, some contractor used Type M (thinwall) pipe.

Another interesting thing I learned about just yesterday! Type M vs. Type L.

Apparently it also depends on the ph of the water...

Also your AHJ and plumber. I want to say in NY we were forbidden to use Type M for anything other than hydronic heating.

I would argue that a good plumber would recommend PEX over piping a house in Type M.
