How does a t-fitting function in plumbing?

A t-fitting, also known as a tee fitting, is designed specifically to connect three sections of pipe together in a configuration resembling the letter "Y." This fitting has one inlet and two outlets, allowing for the branching of a pipeline. It is commonly used in plumbing systems to facilitate the flow of fluids from a main line into a secondary branch line, thereby enabling effective distribution of water or other fluids to different locations, like connecting a vertical line to a horizontal one.

This functionality is particularly important in both residential and commercial plumbing applications, where the system needs to efficiently direct water to multiple fixtures or appliances that require supply lines. The design of the t-fitting ensures that the flow can split seamlessly while maintaining adequate pressure and volume through the pipes.
