The pump will run as it pressurizes your water supply. It should run until pressure is achieved and then it will stop. It will restart when a faucet or flush occurs because this drop in pressure will cause the pump to turn on.
If it never stops, then you are not getting to the proper pressure. I would suspect a leak in the plumbing somewhere that prevents the pump from achieving the pressure it needs, like the water coming out the back you described. That area could be your culprit. You could be collecting water inside the underside cover someplace else which is why you may not be readily seeing it.
It sure sounds like a water leak somewhere.
