Match each plumbing pipe material to its standard residential or commercial trade application.
- PEX (Cross-linked polyethylene)Flexible tubing used for pressurized hot and cold potable water supply lines
- Black iron pipeThreaded, ungalvanized steel pipe primarily used for indoor natural gas and propane supply
- Cast iron pipeHeavy, rigid metal pipe traditionally used for main drain-waste-vent (DWV) stacks and sound dampening
- CPVC (Chlorinated polyvinyl chloride)Cream-colored rigid plastic pipe chemically rated for hot and cold pressurized drinking water systems
Answer
PEX matches with flexible potable water lines; Black iron matches with natural gas and propane supply; Cast iron matches with drain-waste-vent stacks; CPVC matches with high-temperature rigid plastic drinking water lines.
Each plumbing material serves specialized trade functions based on pressure, chemical compatibility, and temperature tolerance: PEX routes flexible drinking water, black iron securely carries fuel gas, cast iron handles high-volume drainage and quiets waste lines, and CPVC withstands heated water under supply pressure.
