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.

dvw pipe = drain, waste and vent pipe.
DWV pipes are designed for drainage, waste, and venting systems, while Schedule 40 pipes are used for pressurized water systems. DWV pipes have thinner walls and are not suitable for high-pressure applications, while Schedule 40 pipes have thicker walls and can handle higher pressure.
Key considerations for designing a plumbing system that includes DWV components include proper sizing of pipes to ensure efficient drainage, correct placement of vents to prevent sewer gas buildup, adherence to local building codes for safety and compliance, and consideration of the overall layout to minimize potential clogs and maintenance issues.
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.
