What color is associated with type DWV piping?

The color associated with type DWV (Drain, Waste, and Vent) piping is indeed yellow. This identification helps plumbers and other professionals quickly recognize the type of piping in use, which is crucial for ensuring the correct installation and compliance with plumbing codes.

Choosing yellow for DWV piping effectively communicates its purpose, as it stands out and is often used in various plumbing applications to provide a clear visual cue. Conversely, other colors are designated for different types of piping or systems, which is why it's essential to understand the color coding in plumbing practices. For instance, blue is commonly associated with potable water systems, while red may indicate fire protection piping, and green is often associated with sewage or stormwater systems. Thus, recognizing that yellow is specifically for DWV helps maintain safety and efficiency in plumbing installations.
