In water distribution, what characteristic is typical of flexible joints?

The characteristic that is typical of flexible joints in water distribution systems is that they allow for limited motion. Flexible joints are designed to accommodate shifts and movements that may occur in a pipeline system due to temperature changes, soil settlement, or ground movement. This capability is crucial for maintaining the integrity and functionality of the water distribution system, as it helps to absorb shocks and prevent stress fractures that could lead to leaks or system failures.

Flexible joints are distinct from rigid connections, which do not allow for any movement and can lead to damage when subjected to dynamic forces. The ability to flex ensures that the joints can adapt to movement without compromising the system’s structural integrity.
