Copper Pipe Types and Applications

The video tutorial discusses different types of copper pipes used in plumbing, including Type K, L, M, and DWV. Type K is the thickest and most durable, suitable for commercial and underground use. Type L is slightly thinner, ideal for homes with hard water issues. Type M is the thinnest and most cost-effective, easy to work with. DWV pipes are used for drain, waste, and vent lines, not for water systems.
