Yes it works harder because you lose energy to the heat and friction you can never regain it while going back down.

However if you have a frictionless hose then W = F*d and as long as you are going the same distance the path does not matter and you will have put into the same work.

So long as there are no kinks or other areas, where the hose is being deformed, then no. For water at high pressures, it doesn’t really make any difference whether it travels horizontally, vertically, or in aloop, the pressure loss through the hose will stay the same. (unless you change the diameter of the hose or make it go around sharp bends.)

Any kinks?
