Air IN leak can ONLY happen on suction side of pump........
Discharge side of pump will cause water to leak out IF there is a loose/cracked line/fitting

Get one or other wrong and pump will NEVER shut off.
Adjustments should be done with pressure gauges and understanding of how bypass functions/at what pressures it opens/closes and how it interacts with pump discharge pressure.
