Pipe - CU, ASTM Type DWV (in)

on . Posted in Pipe & Tubing Datasheets

This datasheet is for Copper Tubing, ASTM Type DWV which is designated with a YELLOW background color coded for identification. DWV stands for Drain, Waste and Vent.  For more information about copper tubing, visit our copper tubing page.

Type DWV

  • Color Code - Yellow
  • Governing Standard - ASTM B306
  • Common Applications - Drain, Waste, Vent, HVAC, Solar
  • Commercially Available Lengths
    • Straight Length
      • 1/4 inch to 12 inch - 20' (drawn), N/A (annealed)
  • Type DWV is thin wall - hard temper only.
  • DWV = Drain/Waste/Vent should not to be pressurized.
