It seems as if you have a leak which is causing the pump to refill the tanks. It may be on the water source side, or the house side. If there’s a means to shut off the water from the tanks, do so and if the pump stops running as it is, turn one tank on and see if the problem returns. If so, whatever that tank feeds, has a leak. If no leaks on the house side look at the source side.
