Why Does Water Flow from Low to High Energy Levels?

[foo9008]

Homework Statement

As we all know , energy will lose from high to low. in the equation , the energy at A ( Pa +za +](Va)^2 ]/2g ) is higher , while the energy at B is lower. So, why the water flow from B to A ? why not A to B ?
20.39 +10.52-hf = 32.98

chek the pressure values -it must be supporting the flow? that's how one pumps water to higher levels!
