In my case it was just ground movement due to drought. We had something similar occur in 3 different areas of the yard. Once it was a coupling between two pieces of straight pipe. I had walked over the area 1000 times (and cars and mowers had driven over it) in the past 2 years, but in Aug, I walked over the area. The first time was the 45 that is at the corner of the house. The third time was at the top of the well-head where the well comes up out of the ground and then there are 2 90s for it to go back down into the ground before it goes to the "pump house" where the expansion tank and pressure valve are.
