I have 3/4 and 1/2 in copper running all over my attic of my 20 year

tubing. Maybe if the copper had been thicker, it wouldn't have
happened. Maybe if it had been bust resistant plastic .....

I still don't know which I would choose.

Frozen pipes will burst no matter the material. The force of expanding
frozen water is incredible. Last winter one of our building had a bad
freeze and iron pipe split, as did the copper. I don't think plastic
would
be any better.

I'm just not sure about the very long term results with plastics. I'm
talking 30 or 50 years that copper will hold up under.
