What does the term 'ty' refer to in plumbing?

The term 'ty' in plumbing specifically refers to a fitting used in a drain, waste, and vent (DWV) system that merges a side branch with a main branch. This type of fitting is essential for allowing multiple drains (such as from sinks or tubs) to connect to a single main drain line efficiently. It is designed to ensure proper flow and reduce potential clogs by directing waste water appropriately.

The use of this fitting is crucial for maintaining effective drainage systems in residential and commercial plumbing. By facilitating the connection between branch pipes and the main line, a 'ty' fitting helps maintain both the structural integrity and the functional efficiency of the plumbing system.

Understanding this terminology is important for anyone in the plumbing field as it not only relates to proper installation but also to the overall health and maintenance of the plumbing system.
