DWV (drain, waste, andvent) copper tube is designated by ASTM standard, the actual outside diameter of this kind of tube always 1/8 inch larger than the standard size designation. In residential buildings and small commercial buildings, the drainage piping is usually straightforward in design and simple in installation. DWV copper tube, installed with good workmanship by an experienced plumber, will provide many years of trouble-free service.
