What is the color coding of PVC pipe?

There are no governing bodies that require specific color coding; therefore, the PVC pipe industry has self-standardized color coding of PVC pipe. Below is the typical industry color coding standard of PVC pipe:

Color Application

Blue

Pressurized potable water

Green

Sewer, both gravity and force main

Purple

Reclaimed (non-potable) water

White

General use – (plumbing, Drain/Waste/Vent, or Water well)

Gray

General use – (typically plumbing and electrical)

Note:

  • There is no regulation of the actual shade of color used. Therefore, based on the manufacturer, the specific color may have slightly different shades. For example, Westlake Pipe & Fittings’ Green PVC sewer may have a slightly different shade than other manufacturers.
  • The color of the pipe material does not affect the pipe performance.
