Air in deep well line
I have been getting air in my water for the last 2 yrs. It comes and it goes. Some days the banging and air is worse than others and some days it is just fine. I installed a 1.5 hp submersible with a 220v power line 15 yrs. ago. The bladder in the holding tank is fine. The pump is coming on and off when it is supposed to and reaching its 60 lb. pressure shut off. I replaced the o ring on the pitless and it didn't help. It is a 6" well that is 385' deep and I have the pump set at 350'. Another reason I know it isn't the bladder tank is when the pump comes on at 40 lbs., I can hear the air comong through the line into the bladder tank. Thanks, Joe A

Air in line
Dear Sir, The original tank had a bladder. I have replaced one bladder since doing the initial installation. With the tank completely drained, I am still reading 40 lbs. air pressure at the bladder air valve. Thanks Joe

The source of air in the water is going to be one of two things:
1. Bladder ruptured allowing air to get into the water side of the tank and eventually into your house. This of course would require that you must constantly add air to your bladder to maintain the proper bladder pressure.
2. Water left in your main line after the pump cuts off leaks out either due to a rupture in the line or a faulty check valve.
From your description your problem is likely #2, since you hear air entering when the pump turns on. I initially suspected that a standard tank was removed and replaced with a bladder tank, but the snifter/bleed valve combination was not removed.
