How to prime a jet pump 

Important: The pump housing and piping MUST BE MANUALLY PRIMED (filled with water) the first time, before running the motor, or damage will result that WILL VOID YOUR WARRANTY.

Note: On existing deep wells, make sure proper ejector is being used. If ejector does not match pump, the pump may not build pressure and may not prime properly.
