I have a galvanized steel tank which has an air ejector control valve on it. No bladder as the pump makes air. The pressure switch for the pump was set at 30-50. Whenver the pressure got near 30 the air ejector valve opened up and bled off excess air. I understand the valve works on water level. The pump turned on and filled up the tank.
I just had to replace a leaking check valve between the tank and the supply line. While they were here they also replaced the switch (old one over 20 years old) and new pressure gauge. The new pressure switch is set at 40-60The air injector valve never seems to bled of any air now.
Questions:
Since the air ejector works based on water level, I'm assuming the change in pressure switch settings has nothing to do with it not bleeding air? The contactor said that the fact the valve opened up just before the pump switched on most times was just a consequence.
Since the tank had to be completely emptied to replace the check valve am I correct that when the tank first fills up it has more water than air? If that is correct that would explain why the water level is too high to trigger the air ejector.
Is it a fair statement than to say that the air injector valve only needs to function when the water level drops below the valve and not everytime the tank refills?
