a CSV will make your pump start and stop while only pumping 1 GPM instead of full pump capacity. Starting and stopping at 1 GPM is much easier on everything in the system, especially the check valve.
The stop part I understand, but where does the start part come from? Upon start up, the pressure has dropped to the low end of the switch setting, and I would hope the valve allows the full output of the pump on start up.
