What plumbing purpose can Type L copper tubing serve?

Type L copper tubing is known for its thicker walls compared to Type M copper, making it suitable for applications where higher pressure and temperature conditions are present. This characteristic allows Type L copper to be effectively used for above-ground drain, waste, and vent systems. The robustness of Type L tubing helps prevent issues such as leaks or burst pipes that can occur under varying conditions.

While Type L can also be used for water distribution, it is primarily valued for its strength and durability in drain, waste, and vent applications, where it can manage the demands of waste piping systems efficiently. Its corrosion resistance further adds to its viability in plumbing applications where moisture may be prevalent.

In contrast, other types of copper tubing have their specific applications which do not align with the robust requirements of drain, waste, and vent systems, thereby reinforcing why Type L is the fitting choice for this purpose.
