I've heard guys say that they mostly use plastic in preference to copper these days - is this the common experience?

PVC and ABS are practically indestructible. Copper is wonderful for water lines in most places, but there are some areas that have minerals in the water that eat copper so CPVC or Pex are used for supply lines. As you can see by the previous post, copper and acids found in drains don't mix too well. Add the very high price of copper to the mix, I can't imagine why anyone would use copper for a drain system. You can see in the above photo the drain is eaten up, but the supply lines are in like new condition.
Thanks for the replies. Hackney, i've occasionally seen degraded DWV Cu. like in the pic. But how can you be sure that it's the, admittedly corrosive, sewer gases? Was the structure on a septic tank, or unusual disposal conditions?
The plumbers in this area who use plastic for water lines are the ones doing the "cheap" jobs.
