> Any pump that is pumping against pressure will draw MORE current. I don't see how a "cycle" valve will reduce the pressure against the pump.
Remember that power is the rate at which work is done. The work in this case is pumping water from the bottom of the well to the pressure tank. Whether it takes two minutes or one minute to refill the tank, the total work done is the same. If it takes two minutes to refill the tank, the average power consumption will be half as much as if it takes one minute. Assuming the power factor and voltage are unchanged, the current draw will be half as much over two minutes as opposed to one minute. This is all basic thermodynamics.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
