A builder I know is offering a choice of plastic or copper plumbing in
new home construction. He recommends plastic as he says it is
quieter. He charges the same for either one. Anything else to
For drains plastic is much noisier than metal. My preferred solution is
cast iron for drains and copper for potable water. For plastic I like
schedule 80 PVC. Some will favor PEX.

Good luck with your builder, I hope it is not KB
I just told them to stuff it and bought another home.
Do you mean they are wet to start? Polymers fail because of stress
cracking, oxidation and crosslinking or plasticizer migration. PVC and CPVC
is cheap compared to copper. PEX isn't. Much depends on the quality of your
water. BTW anyone can learn to properly sweat a copper connection in 15
I'm glad you think so. And even if that were true, let's see

I've seen the plastic lines installed in new construction in our
area and have wondered about the ease with which a DIYer can
come along later and drive a nail through the lines. The light
metal pieces put across the studs won't slow anyone down very
I also questioned the local building inspector's office
about using the plastic lines for grounding the electrical
service. They seemed to think it's OK. (There's a real
ground to ground also.)

It's almost as easy to drive a nail through a copper pipe.
You ground the electrical service to the *back side of the meter*, so it
should be thick-wall copper tubing or pipe. If the water entrance is
plastic, you wouldn't use it as a grounding electrode. You'll have to make
some other kind of grounding electrode.
Yeah...what kind of copper? K? L? M?

A rental unit in which the plastic elbows were replaced with copper
only to have the copper spring a pinhole that brought down a ceiling.

Copper supply pipe makes a lousy club. One hit, and the pipe
is kinked. Second hit (if you're lucky the pipe hasn't kinked
at your fist), you have two shorter pieces of pipe and a pissed
PEX or PB pipe makes a better weapon. Hint: it won't break.
Iron pipe, on the other hand...
Though, if you had time to sharpen the end of the copper pipe,
it might be useful...
