    Or just put a ball valve or even a 1/2" gas cock on the air outlet. That way you could use it to vent the initial amount of air if the system's been drained and then close it off.

    It could be debris in the impeller or it could be cavitation which is cause by low suction pressure. Like a valve closed or a restriction.

    If it is cavitation, the pump won't last long.
