The trigger wand has a mechanism inside of it so that when the trigger is released, the flow of water is blocked. The spike in pressure created prompts the unloader valve to switch into bypass mode. If the seal that stops the flow of water through the wand is broken, water may continuously flow from the nozzle, as the unloader valve will not switch into bypass mode as it should.

When you release this built-up pressure by pulling the trigger on the trigger gun, the pressure inside the pump drops, turning the motor on again.
