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

Plastic DWV for me for 99.9 percent of my installs. My higher end customer want copper(for potable) and I suggest copper if they currently have a copper system however somtimes the job dictates the best type of pipe to use.

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.

The plumbers in this area who use plastic for water lines are the ones doing the "cheap" jobs.

Sewer gas caused that DWV copper to fall apart.

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?

I did the repair and there was alot of sewer gas flowing. It was unusually bad.
The home is connected to a city sewer system.
