Only air

[Steve20034]

I have a 1/2 hp jet pump in my basement. It has plastic pipe and fittings that run to a septic box which fills with spring water. The box is always full of water. I woke up today and no water. I tried to prime the pump but it is still only pulling air. Every connection is double clamped could i still be pulling air from the connectons? There are no water leaks. Thsnks for any help

Probably have a suction leak. A suction leak will let air in, but not leak water out.
