Concept of flow of water:
Water has tendency to flow from a region of high pressure to low pressure.
Also, the external force that acts upon it matters.
Due to force of gravitation, the water from the tap flows in downward direction.
(Diagrammatic representation of the taps connectivity is not provided to answer the question in detail).
Based the given details, the tap that is located at the lower altitude is the last to receive water from the spring at the top of the mountain.
But, based on the pipe length, tap locations and connections, if the pressure at different taps vary, then the answer might change.
When the force of water is higher than the gravitational force, then the water can flow upward.
