Benefit of Material to Systems Application

Copper drainage tube is a seamless copper tube that conforms to the particular dimensions that are commercially known as Copper Drainage Tube, Type DWV. The characteristics of lightweight DWV grade copper tubing make it an excellent, durable choice for use in drain, waste, and vent systems. Type DWV is primarily used for drainage systems and typically found in “hard” temper 20 ft lengths and “soft” temper lengths up to 100 ft.

Type DWV Copper is found in many older systems. Currently cost is a deterrent in using copper compared with plastic pipe or cast iron.  An advantage to using DWV copper is that it is accepted by all codes, has a thin wall, and lightweight and easy to assemble. DWV grade copper tubing has a smaller outer diameter while maintaining good flow characteristics. DWV is convenient in that a 3-inch pipe and fittings can fit in a 2 x 4 wall.  DWV is less labor intensive and also fireproof. Disadvantages include: costs tend to be higher than with plastic pipe or cast iron, copper DWV tends to transmit noise, and it requires nail protection plates.  Another deterrent is an open flame is required to seal joints while flammable material is often present at install.

System Application and Material Usage

Both drain, waste, and vent (DWV) and storm drainage piping systems require ASTM B 306 copper tube Type DWV, with joints soldered or brazed. DWV is acceptable both above and below ground. However, local codes should be checked for underground usage. Solder types and joint strengths should be based on the temperature and pressure within pipe.
