What fitting helps eliminate kinking of the hose and enables the change of direction of the water flow in elevated water sources?

The correct answer, which is elbows, refers to a type of fitting specifically designed to change the direction of the water flow in a hose system. When working with elevated water sources, hoses often need to navigate around obstacles or change angles, and elbows provide the necessary flexibility while simultaneously helping to prevent kinking. Kinking can restrict water flow and potentially damage the hose, so an elbow fitting allows the hose to bend smoothly without sharp angles that could cause such issues.

Elbows are generally used in various applications where a shift in direction is needed, thereby ensuring the hose remains properly aligned and functional. When elevated water sources require strategic routing of hoses, elbows are crucial for maintaining a reliable and efficient setup. The use of these fittings contributes to a safer and more effective firefighting operation by ensuring that the water supply can be delivered where it is needed without restriction or compromise to the equipment.
