Polybutylene pipes don't burst when frozen.

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.
