What direction of flow does bell and spigot pipe face?

In a bell and spigot pipe system, the flow direction typically follows the orientation of the spigot end, which is the male end that fits into the bell end, or the female end. The spigot is inserted into the bell, allowing fluid to flow from the spigot into the bell. Therefore, the flow direction is from the spigot into the bell, facilitating a smooth transition in piping systems.
