Just for fun...

All the water pipes underground and in houses are plastic now.

We repiped our house last month with L-class copper to replace the thinner-walled M-class copper used when the house was built ca. 1987. We were offered PEX (plastic) at 25% lower total job cost but declined.

PEX comes in 2 flavors, A and B. The bidder pushing PEX-A said in a dire tone, whatever you do, don't use PEX-B!! You'll never guess what the bidder pushing PEX-B said.
 
Yes and the way they do it is they munch, get sprayed and run off, then you are left with a fine mist that slowly soaks everything without dripping, the first you know is the ceiling sags and the entire area has turned to mulch.

I installed copper in my friends house rebuild, its a massive job though.

Tip..never do anything for a friend.
 
Maybe in your young state, but not out here.
Okay, maybe just all of the newer ones. I just watched 12" blue plastic ones going in. They are replaced as streets are repaved. One close by one is going from four car lanes to two, it is getting parking between the cars and the outer bike lanes adjacent to the sidewalks. Parked cars will protect the bikes. And one large four-way intersection is getting a roundabout. It is traffic calming of what was a drag race zone, making the neighborhood nice. Trees are also going in. Look at the safety improvements with a roundabout.
