What defines a diverted fitting?

A diverted fitting is characterized by its ability to direct the flow of fluid in a specific manner, typically within a plumbing or heating system. This means that it can adjust the flow appropriately to ensure that heating units receive the correct volume of water they need to operate efficiently. This is crucial in systems where temperature regulation is necessary for comfort and energy efficiency. As such, the role of a diverted fitting is essential in managing how water flows and is distributed throughout a system, particularly in relation to heating units, where precise flow control is required to maintain desired temperatures.

In the context of the other options, while they reference various functions of fittings, they do not accurately capture the essence of what a diverted fitting is designed to do. Options discussing backflow prevention or right-angle connections describe different aspects of plumbing fittings that focus on controlling water paths or flow direction, but not specifically on adjusting flow to heating units. The choice highlighting flow adjustment is quite broad and does not emphasize the direct relation to heating units, which is a critical aspect of a diverted fitting's functionality.
