Water Supply

Copper was still used, but rarely. 

CPVC (cream-color plastic) was the most popular water supply pipe.

PEX (red, blue, or white flexible plastic) especially popular to repiping older homes.

PVC (white plastic) used for water service piping to house (not inside), and other exterior locations.

Drain (DWV)

ABS (black plastic) continued to be used, especially in mobile homes.

PVC (white plastic) was most the common DWV pipe.
