I recently had a bad check valve on my water tank replaced only to find it was masking a more severe problem diagnosed by both my plumber and a well water systems repairman. They believe there is a leak in the line coming from the well to the house that sucks in air when the water is turned on in the house. I have had this air issue ever since (~10 days), the water pressure is normal otherwise so for now it's just a random nuisance.
My first question involves the diagnosis that the bad check valve in the house was allowing existing tank water to flow backwards to the leak (underground) therefore preventing the air gap issue I now experience. Does this sound feasible? The pump would kick on all the time when the pressure in the tank dropped below threshold.
The second question is related to the replacement of the line. Would it be best to put a new line in (starting at the well ofcourse) or try to find the leak by excavating the old line which may run under my deck, fence and retaining wall all installed later than the line? Maybe I will luck out and find the leak 10 ft from the well? Anyone in a similar situation please reply.
thanks.

Boil your water until it's fixed. If it can draw in air, it can also draw in surface water and all sorts of potentially harmful things.

They are 100% correct in their diagnosis and explanation. As for repair, you would want to know the age of the underground pipe, the PSI rating, etc. to make a good decision. You then could start by excavating the leak area itself and try to determine if a rock punctured it, or some other influence and then base a decision off that.
