K, L, M, and DWV are grades of copper tubing commonly used in plumbing applications. Type K is the thickest and most durable, often used for underground and water supply lines. Type L is slightly thinner and suitable for both above-ground and underground plumbing. Type M is even thinner and commonly used for residential plumbing, such as water lines and refrigeration. DWV (Drainage, Waste, and Vent) is a thinner grade specifically designed for drainage and venting systems.

The lowest point in the DWV system, typically where it exits the building, is called the INVERT.
A trap primer line is typically connected to the domestic cold water line, not the DWV system. Its purpose is to prevent evaporation of water in floor drains or traps by periodically supplying small amounts of water. In some cases, local plumbing codes may dictate specific requirements for trap primers.
