Would i need to turn the switch on evertime i need water?
No, even the air-over-water system used the switch only to send power to the pump and the pump senses drop in pressure.
If you can post a picture of the pump and tank, it would help.
The exterior connection may have been a supply line for park hookup. This would have been an easy way to plumb the water supply without pressurizing the tank.
It sounds like you have an on-demand system and a pump replacement is the cure. A picture or identifying name/number will clear that up. Have you tried to turn the pump on?
