Monday, November 22, 2021
Galvanized steel was the most popular water pipe during the 1940s.
Copper was also used for water pipe.
Lead was still used by water utilites for service pipes to houses until the end of the decade, but not supply pipes inside the home.
Copper was used for smaller diameter (up to about 3”) DWV pipes.
Cast Iron was used for larger DWV pipes.
Clay still in use, primarily for utility sewer lines or laterals.
Orangeburg (bituminous fiber pipe) was used for sewer laterals beginning in mid-1940s.
