Need help with water flow through multiple pipes in different directions

WATER IN PIPE.blend (1.1 MB)

I am creating an animation in which water flows from one end and travels through multiple pipes in up, right and down direction and fall into a cylinder. UVSphere is my water source. My water does not follow the pipe path . Help me what can I do? I have attached my blender file so if you can help me fix it, I will appreciate it very much.
