All the water mains installed now are plastic. My only objection to it is it is highly suseptable to damage and prefer to expend the addional money to use copper.

Properly installed and sized Schedule 80 is superior to copper. No electrolysis. Our main is 1-1/2". It's not going anywhere.

Properly installed copper won't corrode or be effected by electrolisis either.

It's legal to use plastic for mains in California up to the structure but must be changed to copper or galvanized going into the house.

Unless plastic mains are covered with a concrete slurry prior to burrying they are still too easially broken, i've had to repair too many of them.
