When is it appropriate to use a T-fitting in plumbing?

Using a T-fitting in plumbing is appropriate for creating a branch line from the main line. This fitting is designed to allow flow to split off from the main line while maintaining a consistent direction of the water flow. The configuration of a T-fitting, which resembles the letter “T,” provides a straightforward method to divert fluid from one pipe to two or more additional pipes.

For instance, in a residential plumbing system, a T-fitting might be used to extend a line that supplies water to multiple fixtures, such as toilets or sinks, branching off from a central water supply line. This is essential in plumbing systems to efficiently distribute water throughout the structure.

Using a T-fitting does not serve to connect two fixtures directly, increase water pressure, or specifically connect a sink to a drain, which are functions suited for different types of fittings or methods in plumbing installations. The focus on branching off from the main line is the key factor that validates the appropriateness of T-fittings in such scenarios.
